I chose the Transformers series, but those movies were pretty hit or miss I thought. The first one was actually pretty good. The second one was kind of awful. (The comedy relief bro robots reminded me of a jar jar binks lol) The third one was actually decent in my opinion though I know many hated it. I don't think it was bad if you looked at it as a separate movie from the others. The fourth one was also bad, though not as bad as the second.
However, since I liked the first one quite a bit, I'm voting A. Despite it being a Michael Bay movie and it being filled with explosions and slow mo, it still had a half-decent plotline and stuff.
