I missed this at the cinema and heard so many good intial reviews on radio and tv,
It reminded me of a cross between Dumb and Dumber and Cheech and Chong -- but it did not work at all.
Based around smoking pot and getting high, there is not much to it and although some things would make me smile to myself, i never broke out a laugh once and I love comedy films.
Im not sure if you needed to be intoxicated to get the humour and that was the point, or maybe our sense of humour and the americans are very different now a days.
In terms of picture, id give it 3 out of 5. to be fair, its not a movie to utilise the power of blu ray, but it was pretty crisp in parts.
Maybe rent first, like people have said previosuly, its very hit and miss.
I hope this review helps
