@mage  all I know are the movies (which include the Christopher Reeve era Superman and Batman up to and including the Nolan variants). I haven’t seen all of the Marvel movies (yet).

To me these movies are entertainment … unlike Star Trek (the JJ Trek is not Star Trek … not even close) I have no real commitment to them beyond a few hours of fun.

Classic Superman movies were solid, predictable and a product of its era, and not too bad. Superman is what he is … a basic goodie two-shoes hero from another galaxy. It’s a bit boring, which is why I don’t mind what they did to him in the re-imagined grim dark variant.

The Jack Nicholson era Batman movies were fun, but I think they also couldn’t decide whether to be deadly serious or fantastic. Which is probably why they ran out of steam.

The Nolan era trilogy … had a good start, but I liked the Joker more than Batman in that trilogy. I also think they kind of missed the opportunity to explore Joker and Batmans’ relation in the second one.
Bane … fun as a villain, but I don’t know the man so the plot or his behaviour made little sense.
Plus the ‘real world’ setting made his antics ridiculous.

So back to SvB.
Lex Luthor should have been introduced in ‘Man of Steel’, because then there’d be a point to his obsession and his m.o..
I get that they were trying to do something different, but he was a bit too psychotic to be believable as the president of a mega corp. Had they shown him in ‘Man of Steel’ in a minor role or something then this push over the edge would have been an easy sell. As it was I had flashbacks to Dark Knight.
The irony is that Bale had already played the perfect psychotic business man in American Psycho.
I’m even tempted to argue that there should have been a Lex Luthor movie *before* batman vs superman.

I can buy Batman going into overkill mode after Superman & the office destruction.
However the snap back to reality as a result of that one word didn’t feel like he earned it.  The guy was already killing people without mercy (I don’t buy the pacifist Batman schtick for a second in this movie)
I think something involving Alfred would have worked much better than a random strangers’ *spoiler*.

And then there’s the three things that made no sense at all and that can be summarized as : Batman having visions of the future.
Sorry … nope.
We’ve spent one and a half movie building a world that has high tech, zero magic and aliens.
And now we’re supposed to believe that someone as rational as Batman gets visions that tell him what to do next ?

btw : I think the post-credit scenes in the Marvel movies are overrated. Yes it was fun the first time, but it sucks now.
I don’t mind sitting in the theatre to watch all of the credits, because it allows me to see/remember what actors and music was used. But to force people to sit or elses they are going to miss potential important plot points of the next movie ?
That’s lame. Why not make it into a tv-series if you know you’re going to do another one already ?

Speaking of Captain Marvel (beware of spoilers) this is rather fun (if a bit too long) review/critique :
