I was the other way, hated Superman when I watched it a year ago but watched it the other night in prep for Supergirl and felt maybe I was too harsh on it before (if I were rating it now I'd probably give it a 6.5 but still no where near as good as Man of Steel obviously)
Gunn's DCU is going to be a massive fail though and early reviews for Supergirl aren't great either.
I can't believe how badly Gunn has dropped the ball, it's been one colossal mistake after another.
Fire Cavill, Creature commandos is your first release, make an awful Superman film that doesn't understand Superman and Supergirl is your second major film instead of something Batman. Corenswet was at least somewhat decent casting while Alcock looks and sounds like a terrible miscast.
