Apparently I'm also giving my thoughts on the shows mentioned. Because..why not?
Doctor Who: It looks interesting. It sounds interesting. People have told me to watch it. But honestly I wouldn't know where to start.
Community: I think I've seen two or three random episodes. It looks alright, I've heard varying things. The specific episodes I saw didn't have a great impact. Might give it a go.
Dexter: Seen it, already caught up.
