Where the fuck did I say Into the Darkness was better than Wrath of Khan? Am I fucking crazy or can people just not read?
And you know, not much really happens in Wrath of Khan. It was a VERY simple story, done really well. That's where Into Darkness suffers by having two big villains.
You said it had better character arcs. Kirk's tragic arc is actually really, really great. We start with a character that does not face loss, and refuses to believe in it. Through some small vulnerabilities the character is shown to maybe be losing his edge (From age, overconfidence ect, lots of reasons). But he continues to grow and overcome--constantly "cheating" any loss that happened from these vulnerabilities through his wits (Almost every advantage he gets is through deception, that's not just a coincidence. It was done specifically to aid the theme.), just like in his youth--you kind of get the sense that maybe Kirk IS different, it's almost like a type of immortality.
Then at the end, just when he's about to sail into the sunset, having cheated loss one more time and asserting he is above it, we're shown than
no onecan really avoid it. The original problem which the arc was built off of, a desire to avoid or not acknowledge the
humanreality of facing loss, culminates in the last scene, as Kirk literally has to face it and watch his best friend die.
So we get this reclamation of youthful prowess throughout the film, combined with the acknowledgement that loss in unavoidable, it's a part of life. It's pretty brilliant story telling. And that's partially because, as you said, it's a very simple story--but it still manages to pull out a ton of depth because it relies on these themes to illustrate how people grow and change (Which is a hallmark of all really good stories--they have a lot of levels they can be enjoyed at, a good story can be simple or complex, a great story is both.).
So Wrath of Khan has an exceptional character arc. Into the Darkness? No.
And not even going to go into social/ethical commentary bit--the questions posed with the genesis device were also great (And they tie into the "needs of the few" theme in relation to the bad effects of science). I saw no deep questions posed by frozen supermen...If the militarization angle was downplayed to get us back as fast as possible to the action.
Again though, it's an action movie, I didn't go for that...meh and I'm not trying to knock the movie too much, I DID enjoy it. I just happen to think Wrath of Khan is probably the best "arc" in the whole franchise and a good example of how you can actually make a great "action" film.
