I liked the ending at first. It was unique at least, instead of that possible cliche happily ever after they were appearing to build up to. I looked up the season finale criticism (as I do with most shows) and saw one of the executive producers who left mid-show had an entire idea for the series finale, which was very different, and much better in my opinion. Instead of Dexter living on his own, it would have made the entire show appear to be a flashback while he's laying on the execution chair, waiting to get the death sentence given. Now I really dislike the ending they chose, haha... Still a great show overall, and the ending wasn't even close to ruining the show.
