Andrew McGregor I wasn't expecting much but I found this movie well written with none of the clunky lines that make me wince. There is genuine suspense and some interesting inter-cultural parallels. The CGI and monster logic are not great but the characters are well done. It's not Aliens or Terminator 2 but I'd say it's more memorable than most.I thought the Afgan characters were interesting with thought provoking stuff about what it's like to be in the middle of a civil war. The tension around the "are they on our side or not" was very effective.The US army characters were a bit stereotypical but well written and acted.I really liked the ending but others might find it a bit grim. Thought provoking to me.

johnceallach I normally do not trash anyone's films but I have had enough !!!! I watched this film from start to finish ! Let's start with the first point ! These "Soldiers" are not Marines. I have served with both services and there are huge differences besides just uniforms ! Second , This film just cut a lot of their potential audience out because there have been way over a million military members that have rotated in and out of A'Stan,Iraq and other places since the war has started not to mention their family , relatives and friends that know what is and what is BS from their pictures and stories . The "Soldiers" are all "TABBED UP" each with Special Forces tabs and also "RANGER" tabs plus CIBS .I do know a lot of SF /Group guys that wore beards so that isn't an issue but you don't pick the wimpiest guy to try and pull that off ! Arabs wear a certain Kafeeh ( head dress/wrap around neck) due to a certain meaning ( religious reason , country rulers etc. ) as far as Camera work, weapon work and action could have been a bit better. The monster well that is a SCI FI gig there so I will shut my mouth there ! I won't comment on actors actions and good or bad they do what the Director/Producers and Writer tells them too and I can respect that ! Here is a War veteran's heart felt appeal as someone who loves SCI FI films even campy ones ! Get the Military part right when doing Military based films as if it feels real then the fiction is easy to imagine as a reality ! The best lie that could ever be told is 80% true ! Any questions please feel free to contact me directly !! Cheers! DOC J

xenomorph44 OK, I barely saw any of this movie, but from what I did see, it was a complete knock off of Tremors! They hunt by sound? No, Graboids do that, not sand serpents. Again, I didn't see this movie completely, only about 10-20 minutes scattered around, but it just lacked the charm that the Tremors movies and TV show have. I love all four Tremors movies and the TV show, and am really hoping Tremors: The Thunder From Down Under comes out. When seeing this I felt betrayed by SciFi (SyFy). They used to show the Tremors movies all the time on SciFi channel. They even had the TV series, until they canceled it after half a season. Only to come out with this six years later! I would have been much happier if they just made Tremors 5 for TV then released it on DVD. Well, at least I have all four movies and taped every episode of the TV series. Oh, that's another thing. They never released the Tremors TV series on DVD. Great job, guys! Just leave behind what the people want and keep making more movies like Sand Serpents! What's next? Probably a sequel, Land Serpents, then Air Serpents, followed by a TV show called Nothing To Do With Serpents, then getting a prequel Baby-turned-Sand Serpents. Plus, what's a giant worm movie without Michael Gross playing Burt Gummer (or a prequel with one of his relatives)?

kiawa77 First, an explosion woke the worms during a firefight between some American soldiers and the Taliban. Apparently there had never been explosions in the vicinity prior to that, there at the mine. Perhaps those worms were imports.Second, you'll hate Andrews. You'll keep on hating Andrews and wishing him death as the others fall. Seriously, you'll find yourself saying, "God, why couldn't that have been Andrews?!" when Wilson gets killed. Don't worry, he gets his, but in a far less dramatic way than you'll have hoped.Third, how can a gigantic worm snatch a Blackhawk helicopter perfectly out of the sky without getting injured by the blades? Seriously.Fourth, they figure out the worms are attracted to sound and vibration. Apparently, someone has seen Tremors! They all climb into a hot-wired truck without checking if it's even fueled up or knowing if it can outrun the worm, but hey... Sci-Fi is Syfy. They even do the whole lobbing-grenades-from-the-back-of-the-truck stunt later in the flick (just like in Tremors). Good grief.Fifth, the worm always has to come up out of the ground about 100 feet and arc down in a menacing way (in the same CGI manner might I add) and roar. Roar! Essentially over-sized earthworms (or dirt-snakes as my husband called them) have no need for vocal cords and certainly would not have developed them. And yet these babies have that pseudo-grizzly roar.Sixth, would someone please make Andrews die?! Seventh, there are just some irritating little tell-tale Sci-Fi things. For instance, when the group is back at the mine, a grenade flies through the window, explodes, blows shrapnel into Kaminsky (who falls to the floor screaming), and everyone scrambles. A few seconds later, the lieutenant sees fit to yell, "We're under attack!" Really? I doubt anyone had noticed...Eighth, if the worms are indeed attracted to only sound and vibration, then why do they eat motionless bodies? This happened in the beginning with Asala's corpse and later when Kaminsky laid motionless while Stanley and Andrews were running away and yelling. The worm ate Kaminsky instead of going for the moving things causing vibrations. At least in Tremors, they stuck true to the fact that standing still wouldn't get them killed ;) Ninth, what's with the kid? I know it's tough to find young actors, especially on the budget they must've had for this film... but COME ON! My cats have a scratching post with more personality that this girl exhibited! She sees her dad blow up and manages to shout a few times, but nary a tear was shed. Wow.Tenth, the final scene is a dramatic one of self sacrifice for the greater good. However, I can't believe an American soldier would get onto a rescue helicopter wearing a suicide belt. If he thought the worm was going to actually come after them, he could've taken it with him and tossed it into the worm's gaping maw instead of hurling himself into it. It was just such a waste... but dramatic! All in all, this wasn't a total waste of time as most Sci Fi Originals are. The acting is so-so, there are some better attempts at character development (which still fall short), and the story isn't bad.... except it was done before. This is basically a rip-off of Tremors (which is a far better movie than this); they took that and dumped it in Afghanistan.Summary: For a Sci Fi Original, it's not total crap and is actually watchable, especially if you have never seen Tremors.
