^ Well, I'm not prepared to defend everything about Superman II (unlike the first Reeve outing, of which I've never heard a criticism worth countenancing). The amnesia kiss is a crummy idea conceptually, narratively, morally, and pretty much every whichway.
Yeppers. They couldn't even bother giving us a reason why Clark did this...especially if he STILL wants to be with Lois! I mean, if they do get together again, would he just never tell her about what he did to her before?
Amy Adams's Lois figuring out Clark's identity right away, and the two of them proceeding as confidantes and partners from the get-go, was one of the very best decisions the DCEU ever made.
Hell yes. Superhero Love Interests get tons of crap (in fact, female love interests in general get tons of crap) for the false conflict they're forced to create from being cut out of the loop. Eliminating that right off the bat was a smart move.
Sadly, they still couldn't be bothered to think of anything for Lois to do in the subsequent movies except be a damsel...
