We really like it because as a group of newbies - four of the five players had never played before - it gives us permission to do things that are really fun but we never really would have found time to do before. We've incorporated poetry reading, table-reading of scripts, songs, and silly tasks (I made my wife pick a real estate lockbox we didn't have the combination for, before her thief could advance to level 2).
So for us anyway, it wasn't anything about Wizards of the Coast or 5e... this is strictly Gygax-level stuff we're playing. But I think some of it is a blowback from many of us just feeling exhausted and discouraged about online life, there is greater appetite for making these sorts of memories and being creative together.
