Non spoiler remark about SS that's probably already been mentioned but I'll say it anyways:
It's like DC watched the rise of Iron Man+all the other Phase 1 movies then conglomerate into the super successful first Avengers movie, then decided a year later 'okay we'll make a backstory for a Superman reboot'. After that DC then decided to try and replicate Marvel's (still ongoing) success and just giving us these giant blockbusters with all the classic heroes and big stars, expecting all the big praise to come from said conglomerate; somehow they didn't realize it was the Avengers' backstories in their standalone movies that drew audiences to the characters before making Avengers 1.
I mean, on the surface it looks cool and makes them money, but BvS and SS don't appeal to anyone looking for a deeper and substantial story. I also don't see them being able to carry on this farce again if they botch JL 1 - the Suicide Squad box office drop this weekend alone is starting to show people are running out of patience with these shallow films.
Movie-wise it was fun and somewhat enjoyable, outside of the corny moments and weak story.
