For me, I think Infinite Stratos isn't nearly as bad as people make it out to be. It's not good, and I have my issues with it, but I've seen worse
I should probably post this to unpopular opinion but, uh, here we go: Neon Genesis Evangelion. It was so god damn boring even when the big scenes were playing out. I tried to rewatch it when it released on Netflix again but without Frank waiting for me at the credits I just didnt care. I know its like one of the most influential but god damn it kinda sucks with the pacing and the story getting up off the ground.
