Should have been much longer

I'll never understand why this movie is so short. This was the last movie in an epic movie series. Until marvel, this was THE franchise. And yet the final movie is the shortest movie. Something I give movies like Endgame, The Dark Knight Rises, and Return of the King credit for is NOT being afraid to be long for the final movie in a franchise or series.

It didn't have to be 3 hours, but why not 2.5 hours? Just 20 more minutes. Plenty of time to give us more of the battle than just the trio running around. Give some of our favorite supporting characters like Lupin, Mcgonagall, Fred and George some more screentime. And just have more of an epic feel to it.
