Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

In truth, there is barely enough story here to make a film.

Excellent characters with emotional depth. My wife, daughter and granddaughter all enjoyed it...and me, too! Very good movie! You won't be disappointed.

It is neither dumb nor smart enough to be fun, and spends way too much time with its boring human characters.

There are times when I just need mental popcorn, so If you are looking for a silly movie, this is it. I love this movie - it's got some great lines and Sam Elliott. This amazing cast is a trivia lover's dream: Rebecca from Cheers, Princess Leia, Beckett from Quantum Leap, Al Bundy, Muffy from Square Pegs, the husband from Maude and more. Bill Pullman is a great supporting actor.I want Sam Elliott's voice to make love to me. To this day, there are times I remember that line "It wasn't sex, it was GOOD!"I give it 8 out of 10 stars for it's genre: chick flick romantic comedy.

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

This is not a profound film, nor is it intended to be. The story starts off simply: a housewife, Marjorie, is married to a doctor, Harry. Harry is part of a family of doctors that is so close-knit that there should have been adhesions among its members. Marjorie is such a dedicated wife that she stifles her inclinations to be a writer to help bring harmony to her husband's family, particularly when they have "family meetings." Marjory has a younger sister who is something of a free spirit, and she tells Marjorie that the best thing for a marriage like hers would be if she had an affair.Harry's older brother, also a doctor, to be sure, is returning to the United States after acting as a missionary-style physician in a third-world country. Naturally, the family wants to hold a welcome-home party, and, naturally, Marjorie is supposed to take care of preparing it. When she's in a market making arrangements for the party, she's picked up by a man who is very sympathetic with her stifled life, and in time, they take a hotel room and have sex multiple times.Spoilers follow.After their last encounter, Marjorie discovers that her bedmate has died. Flustered, she gets dressed and leaves the room with haste, bumping into a salesman. The salesman has been unsuccessful in selling window appointments, and is determined to make a sale to the hotel. Naturally, he sneaks into the room where the corpse is, and after trying to trim a window, thinks that his actions have caused the man to die. Previously, he found Marjorie's identification, and contacts her. She speeds back to the hotel to pick up the incriminating evidence, not realizing that the salesman thinks he was the agent of the victim's demise.As the picture progresses, like any good comedy, the harder people try to rectify things, the further enmeshed they become.There are some fine lines in the picture, and a few plot twists as good as anything from the screwball comedies of the 1930s and 1940s, even though this film wouldn't have passed the Hayes office back then.It's not a great film, but it is a lot of gentle fun.

This movie is the worst thing one could waste their time on. I have to disagree with the people who call this film 'good entertainment' and 'funny' for my friend and I do not feel quite the same way. We too 'ran into the movie by coincidence' but we were walking around or local video store looking for a random movie rather than shopping the bargain bins at the local K-Mart. We took the movie home and watched it, but did not happen to find 'a great little funny movie.' In fact, if the video hadn't been property of the video store, my friend and I would have taken the tape out back and burned it in effigy right at the credits started to roll. This movie was that bad.
