Superman.
James Gunn wants to make a Superman film, and an Avengers film with wars and Mega-Destruction and a Dr Strange Madness film and an Antman Quantum realm film, and a film where the sidekick is absurdly hard and a dog, and some comedically annoying sidekick superheroes/aliens (who we'll call metahumans, so people might be conned into thinking that they make sense too other than because the 'plot' and setpieces has sprawled out of control and they need some others to help out), at least one of whom behaves exactly as you know that a Nathan Fillion character will behave, and one will be extremely serious about Everything.
And then puts them all together in a relentless porridge where money can buy Magic (but we'll call it technology, probably for copyright reasons or to avoid upsetting Arthur C Clarke's ghost).
It's really not a good Superman film. It's about average as a spoof Superman film but the only connection with Superman really is the names - in fact, Gunn basically appears to have decided to remake Guardians of the Galaxy in Superman's World.
There is some atrocious CGI. Oh, and the ending before the credits is applied with a very James Gunn Sledgehammer, which having it 1/10th of the duration would have worked just as well.
The bloke playing Superman is just about okay, although I very much doubt I will recognise him in any other film that he appears in, not the charm of Reeves by any means, and to say he's been on Earth for 30 years, Clark's really not very clued up.
Good things? Brosnahan is okay in a fairly shallowly written Lois, Olsen is blandly bland - Perry White makes more impact in two sentences, Mr Serious (not his real name is actually quite fun in his earnestness, Nicholas Hoult has a ball as Luthor and is very good at playing nutjobs, almost enough to mask that his plan doesn't actually have an endgoal, he's just a megolamaniac for the sake of being one.
Film studios really need to take Ultimate Control away from some directors, and probably bring some new thoughts in to the fold.
