Yeah I don't read comics.. the movie doesn't even have to relate to the comics if it doesn't want to. It's a different, more darker take on Superman.
I liked it, just because it's not faithful to the comics shouldn't be a reason to not like the movie.
Hopefully they go ahead with Justice League, I'd love to see some monster/beast like Doomsday or Darkseid as the main villain in the movie.
EDIT: Also keen if they decide to do a Flash movie, it'll be interesting how they go about it.
