I dvr-ed Scream 3 because I couldn't remember it as well as the first two. I plan to watch it this evening.
I plan to see Scream 4. Not in the theater (because I don't care *that* much about it to pay $30+ for a trip to the movies with DH), but I'll rent it when it comes out.
I feel like I *have* to see it, since I invested time watching the first 3 movies. I did the same thing with all the Saw movies.
