I liked the first season but the second one sucked and after that it didn't find it's feet for a long time, around S4E10 for me. There were some good moments in between like Hank vs the Twins but not much besides that. Especially since a lot of main characters didn't get much development and felt pointless. The final season was good, especially the last 8 episodes(although the opening to Ozymandius left me feeling kind of cheated). It's not bad but it's overrated.
