Mine's not Scream 4, sadly.
As a horror movie fan, I enjoyed the Scream Trilogy a lot, particularly enjoying the self aware, self referencing dialogue which made them stand out from other films in the teen slasher genre.
My opinion is that they should have left it as a trilogy. There is nothing really bad about Scream 4, it is quite an enjoyable film for one watch, but despite the boast of new rules, I did not feel that it offered anything new to the series. It was to me, just not different enough and all the new rules are, is a load of references to the internet, social networks and more up to date horror movies.
That said, it was quite a fun watch, the acting was decent and the story was not too bad, having watched all the others it was perhaps a bit predictable. I still prefer the original trilogy, maybe it's just my age!
