There are two characters that have inspired more cinematic interpretation more than any other. Count Dracula and Sherlock Holmes. They have well defined traits and follow expected patterns of behaviour so in the hands if a skillful writer it can be exciting to have those expectations suberverted. The bad Superman sequences in Superman III sort of touch on this with the fake Kryptonite story strand as a explanation. What Man of Steel does is assume that the tropes of the character are subverted and runs with it with no in universe explanation. It’s like Superman had taken to booze and womanising with no story switch. If done well it would still be questionable because there just aren’t that many Superman films. But it isn’t. So not only is it a bad film it’s a bad Superman film. Hopefully not the first of many.
