If the guy that did the ama and spoiled as much of the movie as he could wasn't lying his ass off - then you've basically seen almost nothing.

know why they fight

That was obvious from the trailer before too. In fact, details don't even matter. They always fight because they step on each others toes. Thats the real reason. Oops, spoiler.

how they fight (suit)

Immediately obvious from the very first teaser from comic-con. And furthermore, uh - duh. How do you think Iron Man is going to fight Captain America? Oops, spoilers.

who will interfere

Seriously? Is this something we need to care about? She's in the movie. Everyone knew this. Do you think she'd not do any fighting? She's wonder woman, she fights shit. Oops, spoiler!

who will interfere with the interference

That's not even a real thing you just said. First, Wonder Woman apparently interfered with Doomsday. Not the other way around. Second, uh, you really think they will just be standing there fighting for an hour then Doomsday comes up and is like "hey girl!" and then they team up? They are likely already "teamed up" by this point, and Doomsday is only part of what is considered "the final fight." Oops. SPOILER.

and that they will have cheesy jokes

It has jokes. I'm sure it has one or two. Every movie tends to. Whether or not it is cheesy is entirely personal opinion. It wouldn't surprise me if that is one of those moments that never makes it into the movie OH FUCK SPOILER AGAIN I CAN'T STOP.

I forbid you to watch it. You are too stupid. If you think all of this is spoilers, you shouldn't have even read the subtitle of the film, it gives too much away.
