a very clever film

i watched this film a while back after having wanted to see it for a long time and i had very mixed responses by the time it had finished. it started as fantastic with the banter between steve coogan and rob brydon about teeth, but then took a somewhat downwards turn in my eyes. in reality it is an incredibly clever and well done film, but i thought it was too well done. i found too much of the focus was on creating the film and the trouble the producers had, and not on actually being a film in its own right. to be fair i think this is what the director intended it to be, but i think that it was the wrong way to do it
