I would refer to this as an average film, this being three out of five. It appears to have got bad ratings which I do not think it deserves. Many films which I consider to have worse issues with continuity (there were a few issues here) have been rated better. I only noted a few plot holes and I think that this was an enjoyable comedy.
Yes, it is slower than others and I would not consider this to be a typical American film, by which I mean that as a compliment. While not a classic, it is certainly worth watching and I am glad I did so,
