It's definitely worth it if you're trying to catch a lot of TV shows you missed or want to see again. The things I don't like is that Hulu randomly changes shows from access anywhere to Web Browser only, and that even with Hulu+ there is still a **** load of ads. Older programs will normally have three 30 sec ad blocks spaced out over the length of the episode, but I found a newer show that had six 1:30 ad blocks placed in it.
Also some shows, even though they are supposed to be available on Hulu, tell you that you have to watch the episodes on the original channel's website.
