You can imagine the events of this film occurring on the other side of town as the events of 'Napoleon Dynamite' take place. The Sasquatch Dumpling Gang shares the same atmosphere as that film, with the same peculiar 'out-of-time' feel with it's mixing of '80s and '90s imagery and props, the same odd pronunciation of the word 'idiot', great characterisation and lots of quotable dialogue.
Other reviews will give you a synopsis so I'll skip that, but this is a fun film. It probably won't become an instant hit but it has, like Napoleon Dynamite, all the hallmarks of becoming a cult classic.
It's not all great though. The acting is a little ropey in places and the jumping about in time of the script doesn't work very well, and there are some painfully cheesy moments which you sense were aiming for ironic but ended up falling somewhere between the two. For all that though it is an enjoyable film, and I really liked it a lot. If you like Napoleon Dynamite you'll probably love this too, but if that film passed you by you'll probably want to skip this one.
