The main issue, I find, that people have with the moe wave is that it's kind of shallow, and sometimes boring (less action) than shows people grew up with. A lot of anime fans are cut from Shonen/90s classics. It's kind of similar to what people deal with when thinking of like SNES/PS1 (JRPG/2D Platformers/fighters/etc) and then look at the current big genres (WRPG/Shooters)
