You know it's a boring comedy when you find yourself laughing only at the lead actors' costumes.
Los Angeles Times:
[Three Amigos is] a goofy delight. It's like a cross between a big-budget Three Stooges movie and a Hope-Crosby road picture, with dozens of old cowpoke gags thrown in to spice up the brew.
The happy-go-lucky Three Amigos is a picture to see when your expectations are down and you've already been to everything that's good.
New York Times:
Three Amigos is likable, but it never really finds a distinctive style. Not quite parody and not quite serious, it's more like a lengthy costume party.
All great farces need a certain insane focus, an intensity that declares how important they are to themselves. This movie is too confident, too relaxed, too clever to be really funny.
If you enjoy brainless slapstick that allows space for irrelvant absurdities like a singing bush and an invisible swordsman, it's entertaining enough.
A few choice morsels of brilliant humor can't save Three Amigos! from missing the whole enchilada.
The script of Three Amigos plays like it was slapped together by a few friends with a tape recorder enjoying a charming weekend at the beach.
It's a calamity of a comedy, the perfect complement to concession-stand nachos con cheez.
