I thought the final season was pretty good, but it did feel like they tried to shove a BUNCH of content into just a few episodes.
A friend that watches it and I were discussing before the finale how we didn't know how they were going to be able to tie everything up in just one final episode.
Overall, I enjoyed the series...but it definitely was a show that I would, from time to time, get three of them backed up on the DVR before finally saying to myself "Well, I need to watch those just because they're taking up space."
