If you loved 'Super Troopers', you'll love this movie. If you hated it with a passion, then you'll also hate this movie with a passion. Both of those films are the types of comedies best watched with your buddies, or drunk, or stoned, or all 3 of those elements together. ;)
Regardless, I'm glad Jay Chandrasekhar returned to doing films with his 'Broken Lizards' gang of comic buddies. He tried to go mainstream with 'Dukes of Hazzard' and it just sucked.
oh, i almost forgot. plot of Beerfest? well, if you can call it a plot, LOL, basically, a bunch of buddies joing up to represent team USA in the annual Beerfest competition held secretly in Munich during Oktoberfest. Its a worldwide competition of Beer Olympics. Hilarity ensues. On a general movie scale, its probably just a 5/10 in terms of acting/story/etc, but in laughs rating, its a 7/10.
7/10
