Before I start this review, I will warn you that it WILL be biased... I first watched this film as a young teenager, with a group of mates, probably high, and I loved it! Since then I must have watched the film 20 times or more, it's one of my favourites but I'll try to write an honest review all the same.
Like many British films, this is rather querky. There's a lot crammed into quite a short film, and as a result the film doesn't always flow very fluidly, but it's a fun ride if you don't take it too seriously.
Some big faces (Catherine Zeta Jones, Sean Pertwee, Ewan McGregor) give some really solid performances in this movie, but on the flip-side some lesser known actors (if they even are actors) give some performances that wouldn't seem out of place in a school play.
There is a varied and excellent soundtrack to the movie, good enough to stand the hairs up on the back of my neck at times.
I rated this film with 5-stars because that correlates to "I love this movie", but if I was giving a critical rating it would be 3.5 to 4 stars. The music is great. Some acting is very poor, but some is very good (Peter Gunn on ecstasy, great!). Some of the plot is weak, but the underlying plot is very strong. The film doesn't take itself too seriously, so the viewer shouldn't either. Watch with friends, alone, or with a partner, and this film should leave you feeling pretty happy with life.
