I just got back from watching it.

(SPOILER)I was going to write a long ass review, but I'm tired, so I'm just going to go over some points. I didn't like it. The movie as a whole had strange pacing issues. There are quite a few scenes that felt random. I was okay with Henry Cavill in Man of Still, but his acting is just bad here. It's most noticeable in that part where he stops batman in the batmobile. That trout was wooden as smurf. I was worried about Eisenberg from the jump and his performance here didn't appease me. He cannot play old calculation, smooth and suave as smurf Luthor. Gal Gadot was so so. Laurence Fishburne is too good for the film. Batman was okay. The fight we saw in the trailer seemed shakier in the movie and didn't have the same effect as it did in the trailer. That second trailer did show the end of the movie pretty much and that climax was just eh. Those Justice League hints were out of place as well as WW.

I basically agree with these guys.
