They should have stopped making these after the first one - there are only so many times you can watch this chain of events before it just becomes utterly ridiculous, which this film is. I absolutely loved the first film, hated the second, and would say that this is only marginally better than the second.
When your opening scene is a guy driving down the motorway towing a giraffe in a trailer, you pretty much understand what the rest of the film was like, and I wasn't wrong.
It's just slapstick madness and that's just not my bag I'm afraid. Here's hoping they don't make number 4 - although I'm sure they will.
