merklekranz Enjoyable on several levels, "Sibling Rivalry" is the type of black comedy that can withstand the test of time. In other words the lively script will never seem dated. The cast is uniformly excellent, and the dark subject (adultery caused death cover-up) is terrific material for this type of comedy. Bill Pullman absolutely steals the movie with a character similar to the one he played in "Ruthless People" If you enjoy dark comedy then this is a must see. Carl Reiner has come through with another winner that is perhaps under the radar, but deserves to be seen. It will definitely hold up to multiple viewings, which is only one sign of "Sibling Rivalry"'s excellence. - MERK

Laura Hands down, one of the worst movies I've ever seen. The premise was lousy, the script was dull, and the performances were mediocre at best. At no time did I feel like I had been pulled into a believable excerpt from the characters' lives, the way a good movie's story should make the viewer feel. I was always aware that I was watching a group of actors trying to work with some of the worst material in Hollywood history, and not succeeding.On a deeper level, it simply annoyed me. Adultery is not the solution to marital problems; it just makes more problems. Yet to watch this movie, you would think that the best way to combat boredom in your relationship is to have an affair. Then everything will be all right again! It doesn't work that way. Overall, I was profoundly disappointed by the entire thing. I watched it in the dollar theater and I felt like I had been overcharged.

RUKIA22 Regardless of the negative comments about this film I think Sibling Rivalry is a brilliant comedy. The all-star cast were fantastic and hilarious in their roles and boy was it really funny and entertaining throughout. This is a really great movie that will keep you laughing although there are some serious drama in between this is an enjoyable film. Scott Bakula is the only reason I watched this film in the first place and I thought he was just brilliant. Scott plays Harry who's from a family of doctors with Carrie Fisher as Iris she plays his sister and Harry's brother is played by Sam Elliot as Charles. Kirsty Alley is beautiful and fantastic as Marjorie she's just married to Harry and happy for a while until she grows bored and frustrated that they never make love. Unhappy and unsatisfied she meets a man in a shopping store this soon leads them both to a hotel room where she spends the night with him. After that what happens is through funny consequences and it's completely funny. The whole cast do a brilliant and are all great fun to watch. I'd give this film a try if your just looking for laughs because I certainly enjoyed this film very much.

jehu23 Carl Reiner went from gems like Oh God, The Jerk, All of Me and Dead Men Don't Wear Plaid to this piece of trash. I am a fan of Scott Bakula and Kirstie Alley, so I was looking forward to this movie, but Reiner only has the makers of 2003's Cat In The Hat to thank for preventing this movie from being the worst of all time in my opinion.Only movie I have ever walked out of... just horrible.
