I re-watched the entire Scream Quadrilogy over the weekend (such a great film franchise). Also, spoilers ahead if you haven't seen all the films:
Scream - 9/10
My fave horror film of all time, love the satire, the razor-sharp humour, the opening scene, Sidney as the Final Girl, the amazing characters and pretty much everything about the film. Really well directed, very tight and cohesive, a great villain reveal and satisfying conclusion. I'll always love this film.
Scream 2 - 6/10
I know a lot of people find the second movie to be as good as (sometimes better) than the first, but there's something about the second film that just doesn't gel with me. I don't particularly like the opening scene, and while I enjoy some of the new characters (Derek, Micky, Mrs Loomis) some of them are really annoying (Haille, the sorority sisters, Gale's new camera man). Cotton Weary's characterisation in the film is ... weird, to say the least. I know he was supposed to be a red herring, but I feel like they went too far with it. Also, the third act of the film (pretty much from Randy's death to the end) kind of drags a lot. Still a fun watch, though.
Scream 3 - 7/10
The third installment is much goofier than the preceding two and not nearly as well-written, but I still love it and enjoy the hell out of it when I watch. I particularly love Parker Posey's character and all her histrionics. I enjoy the comedic elements and I like the cheesy soap-opera backstory which is developed in this film. The villain reveal is a bit of a let down, mostly because even though he's connected to Sidney, they've never actually interacted, so it rings hollow. But it's such a fun film which knows that it's not as good as the other two, and so just has fun.
Scream 4 - 8/10
This one took a while to grow on me and I still think it works better as a gateway to a new trilogy (as it was originally planned to be) than as a finale to the series, but it's a very well-written and well-directed film. I like seeing Sidney, Dewey and Gale as older and more developed characters and I like a lot of callbacks to the original films. Jill could be a better-developed villain, but she's still fun and while most of her friends are a tad under-developed, they're still entertaining characters (especially Kirby!). Overall a solid film.
