Running Scared (2006)
This has a high score on IMDB, a solid cast (and Paul Walker), was made by the bloke who made The Cooler, and a pretty good premise (a gun goes missing, Walker's low level hood has to find it to save himself grief), but the dialogue is so cliched and terrible that I couldn't stop laughing
It also never knows when to stop, and has about five endings. The last of which made me actually shout "oh fuck off willya" at the screen.
There's a really laughable subplot where Vera Farmiga stumbles upon a house with a peadophile couple shooting their peadophile films, and instead of shopping them to the fuzz, she of course shoots them both in cold blood, and just walks off. I mean, they deserved it, but she was a housewife five minutes previously, not the bleedin' Punisher
Some Bloke From The Sopranos is the main mob boss, and his final scene is so over the top and hammy it becomes hilarious. A kid points a gun at him and he goes "Whatcha gon do wit dat, you Cheerio-muncher!" Unless I dreamt this bit, but I really don't think I did. Cheerios were mentioned.
Anyway, RIP Paul Walker, sweet angle, but you were an appalling actor, and this film was a big load of skiddies
