The notion that a reboot like this "confuses the general audience" is nonsense of the tail-wagging-the-dog variety. Very few people in the general audience will be confused because - Shocker! - they've never seen The Wrath Of Khan
or given whatever they've heard about it more than a passing thought.
I think there were ideas from that movie that could've been salvaged and presented in a different context.
No one's interested in salvaging stuff from a twenty five year-old bomb.
