I liked Donnie Darko, but I'm a bit biased. How to explain this without giving away too much...
One thing that I really like in plot is in this movie.
Also, I'm not looking forward to Dodgeball, nor am I particularly looking forward to Catwoman.
I do want to see King Arthur; why will it suck?
Also, there is one scene in The Chronicles of Riddick that was completely worth my entire $5 (or your $8--whatever). If you've seen it, then you know. If you haven't, then... well, I'm not going to tell you, as it isn't nearly as funny without actually seeing it. Unless you enjoy entertaining (not specifically well-made or well-acted [I'm not complaining on either front, but I've been told that I'm a bad judge of a good movie.] but entertaining) movies, you probably won't want to see Riddick.
Note that The Chronicles of Riddick is the sequel to Pitch Black. I have seen Pitch Black but did not realize the connection until after the movie was over... Just so one of you won't fail to make the connection as I did.
