It's actually touching. Once, of course, you get past the sheer silliness of Matt Damon and Greg Kinnear as conjoined (not "Siamese" -- they're Americans) twins...it's a rather sweet little film. I mean, conjoined twins by default have to be identical, right?
It's a buddy picture in extremis; these guys have never been alone. They've always had each other to lean on...literally. They are athletic; in high school they wrestled and played baseball and football, and as adults play goal for the local hockey league. And they have dreams...Walt wants to go to Hollywood and be an actor. The two are nothing alike. Walt (Kinnear) is a blond player, while Bob (Damon) is a shy introvert with an Asian internet girlfriend. While Walt wears sportcoats and button-up shirts, Bob wears polos and rugby shirts.
But it says a lot about attachment. To siblings, to friends, to loved ones...it's really rather sweet.
Cher rather snidely plays herself, and Griffin Dunne and Meryl Streep make appearances as well (along with several others, including Cam Neely). It's a little long, at 2 hours and 15 minutes...but it's not at all a stupid movie.
I saw Bobby Farrelly play goalie once at one of Denis Leary's NHL Oldtimers vs Hollywood All-Stars games in Worcester. He wore number 69 and wore a beer hat over his goalie mask...but he played quite well. Stuck on You is kind of like Bobby playing in goal: ludicrous on the surface, but quite serious underneath.
