Too many characters who need not be in the movie at all.
Hawk girl or whatever she was called was just a girl who makes a weird bird noise and the movie would have been the same without her.
The guy with the weird blonde hair, Guy, green lantern or whatever his name was, was not funny or entertaining and he just looked like an old man in fancy dress.
The black guy with the mask on parts of his face was good though and they made use of his character. Maybe a spin off?
The little gremlin type thing that grows huge was awful CGI, I thought I was watching a kids movie.
The blonde working at the paper and the other guy, older one not the one who helped Lois were both pointless. They did nothing to enhance or even contribute to the movie.
And what was the point in Supergirl or whoever she was as his cousin? Where was she when all hell was let loose? Partying apparently.
Lastly, it felt like it was never going to end, then you wait past the credits just to see superman sitting there doing nothing for about 5 seconds.
