In DC, the best one I'd say is the Batman series by Nolan. Green Lantern was horrible in my opinion. Man of Steel was, okay but little too dramatic. Old superman movies were good.
Marvel, I liked the old Spiderman movies, I haven't watched the Amazing Spiderman. Iron Man series was awesome, with plot and humor. Hulk was okay. Captain America was pretty good, I enjoyed it. Thor, ok. X-Men series, were amazing, I really liked it, and Wolverine. I liked the Avengers the most I guess, the humor and action. (btw who was the guy behind everything at the end of the movie? my guess was red hulk idk)
They're all just my opinions, and I'll be looking forward to more Marvel and DC movies
