I have so much love for DC but after Batman v. Superman, I walked away thinking Marvel might actually be the better company (and I absolutely despise them, so that says a lot
) What really ruins it for me is that Zack Snyder is directing and I think they'd be better off with someone else, just my opinion. That being said, the trailer for JL already looks a million times better than BvS but I'm cautious with spending money to see DC movies in the theater right now after the let-down that was BvS (still debating whether or not to see Suicide Squad or wait a while on it even though that's a David Ayer film). 
Anyway, it looks pretty good, and I got super excited seeing Cyborg
(hopefully this will lead into a future Teen Titans movie? *fingers crossed*) So I'll probably end up seeing this a few months after it's released since I don't want to shell out money for movies I might not enjoy.
