What a weird season.
If you take it scene by scene, the writing and characters still shine. But when you look at it big picture, man, the plot is a mess. So much is misdirection that doesn't really pay off because there isn't enough narrative or thematic follow-through on so many of the plot threads.
By the end of it I also felt like the heart of the show has grown a bit too cold and embittered. I get that that is part of the point, with Veronica becoming older and her foibles becoming more detrimental to her relationships and life, but yeah. I don't know. Kind of a tough season to watch, even though it was frequently entertaining and interesting.
Anyways, even with its merits I don't think I will watch this season again. And I say this as someone who has watched all the other seasons like 3 times. I don't think this is worse than Season 3, per se, but there is an unpleasantness to it that I don't particularly want to come back to when it coincides with a story that tries to condense the serial and episodic aspects of Veronica Mars too much into one thing that just doesn't work as a good overall story.
