Contrary to popular opinion, I think it gets better in later seasons

I understand the sentiment for seasons 1-3'ish, but a little lost about all the hate for the later seasons.
I liked all of the characters, antics and plots each later season till the end. There were many I found annoying but in contrast to the usual cast, it kept it interesting. Specifically speaking, I loved Stu Biggs... had me laughing the hardest of all seasons.

The irony of Hank's alleged goofball son (Levon) played out well too, although he initially came across as irritating. The irony, just like Becca's personality and contrast seems to be the formula that works with the show. I even enjoyed Rick Rath (producer) and Julia (Heather Graham) down to the end. With what they were doing with their evolving stories at that time, I actually didn't want the show to end.

Overall, the ending of the series was a let down, but I only say that because I was enjoying it so much and it felt forced and rushed at the ending.

I humbly admit, I've watched the complete series, I think, about 4 times through. I think it's aged well and the characters are so dynamic, over the top and well played, that it is entertaining and grows on me more with each watch.
