I've been using the Hulu app on Roku for the past few months, and it's one of the best and worst things ever.  It's great because it streams tons of content and even has some good original programming.  It's bad because it's terribly designed.  For one, it's god-awful slow.  It feels like it might be trying to do too much at once.  All I really want is quick and easy access to the shows I want to watch.  I don't need the constant reminders about documentaries and cartoons.  It's also very unresponsive to clicks with the remote.  It takes a while to play or pause or do anything.  Finally, why are there commercials when I'm paying for Plus?  I realize my paid subscription gets me access to more content, but why show me commercials?  That's stupid.  Also, one major missing piece:  CBS.
