Tbh, nobody who complains about it ever really explains what they dislike about it. They just say vague stuff like, 'RT ruined Monty's vision'- even though they have no idea what Monty was planning... Actually, there are some who have very specific complaints, but said complaints are homophobic/shipping related. Safe to ignore those.
I watch it on release. There are definitely things that could have been done better, but it's still worth watching.
I'll admit though, my absolute favorite thing about it is the music. To this day, I still regularly listen to and even sing along with RWBY music.
