"II was a great sequel because it was always intended, woven into the storyline, and filmed simultaneously."
Interestingly enough, the "Turning back time" plot point was originally set to be the ending for the second part.
And for the record, I thought the effects and acting in part two weren't up to par with part one.
"Yeah, I was gonna say, I'm sure Batman and Superman have gone toe to toe like this before...and if I recall correctly, Batman won somehow - any comic book nerds wanna back me up on this?"
Batman claimed he had placed a bomb on a citizen of Gotham, and would detonate it if Superman tried to take him.
As it turned out, Batman was technically correct: he had placed the bomb on himself - he would never take the innocent life of another.
