I love it. A pinch of humor and lovable songs, with incongruity. It is a great ensemble piece.
Memorable songs such as: "sweet tooth", "a hatful of dreams", "you've never had chocolate like this" and well known songs "oompa loompa" and "pure imagination".
It is a brilliant film, in my opinion, but it is very odd and quirky which are films I generally love, however this might not be for everyone. As others have said if you take it on it's terms you should enjoy it.
