Agreed.If you liked Man of Steel you would not like this so that makes sense.
I liked Man of Steel, but I do think it fundamentally got Superman wrong in a way this one gets it right. That said, this is not a perfect movie. Personally I could have used a lot less Crypto and a lot less proton river.
My caveat is that I love Nicholas Hoult. He might be my favorite actor. I thought his Lex, Lois, and Clark were all perfectly cast.
Gunn was clearly inspired by the original films, which were incredibly light hearted and goofy, but he managed to vastly improve his Lex Luthor making him a more compelling villain. Snyder was creating a Superman that would fit seamlessly into a world one step adjacent to a Nolan Batman. I think DC projects as a whole work better when the differences between Batman and Superman are more stark.
One of the core Superman themes is the message of hope. I never felt hope from Man of Steel.
