I know I'm a little late to the game, but I posted a review of the last season on YouTube today.
I've been doing TV shows reviews fairly regularly for a few weeks now and they seem to be going over pretty well with people. I'd have done it for TDRotI, but I didn't get into doing my reviews until the season was mostly over. So I figured an overall review would have to do.
If there is a season five I'll do my normal individual episode reviews.
