As long as you walk into a Feast movie knowing what to expect, and you're cool with that, you should definitely have a pretty good time.
Having said that, here's a list of what the Feast movies offer: Ridiculously over-the-top carnage, broad stereotypical characters who (mostly) behave just the way the movie fans like, an absurd sense of humor that feels like Mad Magazine mixed with some crazily violent graphic novel that your mom would never let you read, and just enough of a "run for your life" plot construction to keep the mayhem moving forward. Best of all, the Feast flicks wear the pulp like a badge of honor.
"There's a place in the movie world," this trilogy says, "for really outlandishly silly monster mayhem ... with extra gore on the side." And I'd mostly agree, but while I had no problem enjoying Feast 3: The Happy Finish for precisely the sort of low-budget video-flick sequel it is, I'd have to admit that (even on the Feast scale), the third chapter is a slight disappointment. Certainly not a terrible little splatter sequel, stocked as it is with ravenous monsters, stupid survivors, and a tongue-in-cheek gore-slinging' vibe that's still fairly infectious, but still ... it just feels like the money ran out a little quicker than expected, and the result is a Part 3 that holds up just well enough, but never manages to improve upon its predecessors. (It could have something to do with the fact that Feast 2: Sloppy Seconds and Feast 3: The Happy Finish were put together as one project, but the series merely plateaus in its third chapter ... when it really oughtta fly.)
As any youthful horror geek could tell you, Feast was about an isolated and grungy bar in which the patrons must withstand a horrific attack from ultra-violent (and horny) monsters. Produced as part of the third (and final) season of Project Greenlight, Feast proved to be a big hit with the genre fans once it hit DVD, and since we're talking about a Dimension (Weinsteins) product, it was no shock at all when those sequels were announced. Sloppy Seconds brought the ickiness into a neighboring town, and now The Happy Finish takes us, well, under the town. The plot is absolutely meaningless, frankly, as the whole point of the trilogy is simply to see if anyone survives.
Picking up directly where Part 2 left off, Feast 3 opens with a few nasty surprises, but the holes in the ensemble are soon filled by a colorful variety of genre-friendly characters. Our beat, bruised, and bloody survivors (Bartender, Biker Chick, Slasher, etc.) are still trying to get outta Dodge, but they come across some allies called Shitkicker, Prophet, and Karate Guy. But the flick is so darn silly that you could easily overlook the sly, movie-geeky intelligence at work here. The Feast flicks are like R-rated matinee movies that are hyperactive, addicted to sugar, and allergic to Ritalin. One could easily poke holes in a few ripe performances, a handful of sketchy effects work, or a plot that leaps from battle to bloodbath with little in the way of logic ... but then you'd be knocking an unapologetically goofy B-grade movie for doing its job well.
Virtually mindless, unabashedly vulgar, and knee-deep in the childish side of the horror pool, Feast 3 is still a good deal of fun. Not as tight as the first one, and not as crazy as the second, but good enough until Part 4 shows up, anyway. For more laid-back fun, feel free to spin some of the audio commentary in which director John Gulager, producer Michael Leahy, and screenwriters Marcus Dunstan and Patrick Melton share their anecdotes and mock their wacky little movie. Also included is an 8-minute piece on director John Gulager, and a collection of all three Feast trailers.
