This film really misses the mark on most fronts. The accents are laughably weak, the acting amateurish and the comedy weak at best.
They've got a great idea, it could have been particularly enjoyable but for the reasons mentioned above.
The writer seems to think by putting the word f*ck into every sentence it'll make it funnier and the main character just seems to try a little too hard. He's no Brick top thats for sure.
Next time at least get a cast that can keep the accent for the whole film.
It's a crime to compare this to films like The Business, Lock Stock and Snatch.
