Scream 4

I loved the opening.  After that, it gets a little tedious for the bulk of the middle.  But it's got some great one-liners and the finale is pretty damn edgy and dark.  Also,  typically well-acted by a good looking cast I've never seen before (a Wes Craven hallmark); and shot just like the other three, so it has the "Scream" look right away. 

I probably liked it more than most.  7/10.

One of the movie's best lines,

"You don't have to accomplish anything anymore (to be famous).  You just have to have fucked up shit happen to you."

Olivia !!!  

Meh.  The first one was original.  The sequels are all higher-end versions of Scooby Doo episodes, i.e. "Let's see who the killer really is!"
