Well, I'm just talking about the logos. Though I admit 2 may be my favorite season but it may mix with 1, depending on how much I miss seeing Cat Grant on the show.
Season 2 logo kinda has that 80s sci-fi retro look, I guess that's why I like it. As I said, 3 is my runnerup choice. 4-5 seems to be most popular but I'm still not feeling the bunch of colors on it myself. It looks ok but for me, not the best title card.
