I know, I've been pretty obsessive about RWBY lately, to the exclusion of much else. I am going through some deep fandom feels here, okay? I don't really understand it myself, but it sparks joy for me, so I'm gonna go with it.
I was really skeptical when I heard that RWBY was doing a crossover movie with Justice League following Rooster Teeth's acquisition by WB, but I bought it to support the show and... it's actually pretty good? It's obvious a lot of love went in to it. It'll give people unfamiliar with RWBY a decent crash course on the world and major characters, there's lots of cool new looks for the DC heroes, and the story stays really true to the themes that have kept RWBY going for 9 years. I didn't actually expect to like it, but I did.
Also? FrostBat and KnightLight are ships now.
