Veronica Mars
Season 1: It took me a few episodes to get into it, but once it did I thought the season was excellent.
Season 2: Way too many clues that left me extremely confused and I thought the Big Bad reveal in the last couple of episodes came out of pretty much nowhere. At least in season 1 we got to see so the reveal at the end wasn't completely shocking. The season 2 character was starting to become my sister's favorite (though I honestly never really saw the appeal) before we found out they were the bad guy. Still, I enjoyed watching this season overall.
Season 3: Lots of Logan/Veronica, which I liked, but not as much Wallace or Mac, which I didn't like.
Also, I laugh at how badly the town of Neptune wishes it was Palo Alto. The wannabe-Stanford Hearst College, rich people owning software/technology-related companies, the spoiled rich teenagers who think there's nothing else to do in town but drink and do drugs, the actual slideshow about Palo Alto in a season 2 episode...the list goes on. For the record, Palo Alto is way cooler than Neptune, and not just because Neptune doesn't actually exist.
