, and I wish we got a few more phone calls. However, it has the best atmosphere, an amazing Neve Campbell performance, and it's the most eerie of the franchise for me so it is my favorite sequel.
I really like the opening of 3 and I thought Neve and Parker Posey were the standouts of the film. I'm also a big fan of the final act (if we are ignoring the awful killer reveal), the cinematography, and Sidney's near-breakdown in the movie. It is a bit underrated even though it has a lot of flaws.
I have way too many negative things to say about 4. I won't even go there.
