I enjoyed the hell out of the first Transformers. It definitely felt like a fun action movie that would spawn sequels going deeper into characterizing the Autobots, with some more genuine species to species dialogue that would follow in sequels between Transformers and humans much like you would see in the cartoons.
Buuuut that didn't happen... still best of the 3 for its potential.
Spiderman 3, yes there were some crap decisions in this movie, but its soooo much fun to watch sometimes (especially the Sandman Subway fight). There was a genuine revenge plot to be had, and although the script was bad I could tell the actors still put a lot of heart into what was on the script. And another thing... the reason I harp on Amazing Spiderman so much is not just because it lacks the charm of the original Raimi films, but nothing memorable came from it. Spiderman 3 though...
Stupid? Yes.
Iconic? To this day!
Also people disliked The A-Team? That's a shocker, that movie had a ton of soul in my eyes.
