Number one, the epilogue was a basic part of the story, the closure of it.

Number two, it seems like they have never seen a 37, 38 yeal old person. They look even younger than they made the characters! Jeez, I'm older than that and look younger than they made Hermione and Ginny (well, I look younger than my age, but much more to my point).

Even though they meade a much better job with the remake, they could still have made it much, much better.
