If it was only season 1, I would rate it a 10. The first Seasons is why I fell in love with the show. The type of humour is my absolute favorite, and I loved Penelope, I was very disappointed when I realized she wasn't in any other season. Well, she appears in S2 and 4 but only for a couple episodes. She was such a great complement to the character or Chip.
S2 was pretty good, not as good as the first one, but still pretty solid. S3 has really good moments, I particularly love the episodes about the opera, the trip to vegas and when they want to film the commercial for the rodeo.
S4 however was a major dissapointment. I felt like nothing happened, everything was skippable, and from season 2 onwards, Chip is just less and less as a clown.
Also I didn't like what they did with the characters of Martha and Dale on S4. Martha is now sort of aggressive which is nothing like her in previous seasons. Dale is now this weird stereotypical republican trailer park 2nd ammendement crazy guy and I dont know, I didn't like that, nor did I find it funny. The only episodes worth watching are the first and last one. But even so, it didn't feel like it got a proper closure.
And also, one of the reasons I fell in love with the show was that it didnt have any jokes relying on current politics and social stuff, in seasons 2 and 3 there are a couple jokes like that, but in season 4... Too many, I mean, for this show it was too many, so unfunny. Like the whole situation with dale in the restaurant... cringe.
However, Christine is the only character that remains perfect all throughout the show. I have never ever seen such a great portrayal of a woman, by someone who is not a woman. It is beyond fantastic. He doesn't try any weird mannerisms or be or sound feminine and exaggerated, and still it is as if he was an actual mother. Sometimes I just can't believe how good Louie is in this role.
