Finished it a few weeks ago. I thought it was a fitting end, I'm glad he got some closure with Princess Carolyn, his final conversation with Todd was great, and I can appreciate the way him and Diane chose to just let things go. The penultimate episode was amazing as well.
When I started the series back in 2014, I never expected it to perfectly capture so many serious subjects like addiction, depression, etc. and do it surrounded by layers of animal puns and running background jokes.
Not to make it sound smarter or better than it really was, but I like to believe I learned a lot about myself and people around me from watching the show.
