This doesn't. It's different.
Life goes on.
That's the thing that drives me nuts about fans. If Feig had done everything exactly the same -- costumes, props, car -- people would be bitching, "Well, if they're just doing the same movie all over again, why bother?" Feig changes things up, and everyone's bitching, "That looks nothing like the original!" It's a lose-lose proposition.
The movie will succeed or fail on its own merits, not based upon how much it adheres to or differs from the original. Jesus Christ.
If they didn't want people to compare this to the original they probably shouldn't have done a remake.
Sure they can. No one says you need to compare it to the original, just judge it by itself. Parents don't judge a second child in comparison to the first, they look at the child by who he/she is.
