Watched again, still feel the same.
I went to see this when it was released and I came out the cinema feeling a bit hmmmm.
Watching it again, it's good fun but there's certainly something a bit off target. The script is terrible and I don't mean funny terrible, I mean just flat, completely unmemorable and a bit amateurish.
I get what they were going for, a modern spoof take of the 50's B movie but it all came off more as silly rather than funny plus the bloated cast doesn't do much for the film past the 'spot the celebrity' novelty.
I think after the success of Ed Wood (which I think is one of the greatest films of all time and really did capture a B movie feel!) and Martin Landau's award, people were dying to work with Burton because he was heading for proper film making fame amongst the greats but Mars Attacks just seems like a mish-mash of colourful gags and some bad tongue in cheek humour and saying it's deliberate doesn't make it any better.
As I say it's fun and there are some good bits like Jack Nicholson seemingly doing a Beetlejuice impression for one of his roles but for Burton it's a big step down from his earlier work which were all Stellar.
