I was curious about RWBY when it first came out and my brother showed me the trailers. But when I actually watched it, the characters were so different from the way I'd imagined them based on their art/designs, and I didn't like the voices or the CG. So I dropped it partway through season 1.
After Judai was raving about how good the latest season of RWBY is, I found myself giving it another try. And now I'm marathonning it. XD
