Yeah, a bit dissapointed about the second episode, but it wasn't too bad really. I agree with you about some of the cliches and specialy the introduction to Weiss. I had hoped they didn't do the rich brat thing. But hopefully, there's still more to come, so maybe she will have a better characterisation. As for the positive stuff, I do agree with you on the small sister interaction between Ruby and Yang and the interaction between Jaune and Ruby. And like the first episode, I still find Ruby adorable.
Since you said episode 3 was better, i'm going to watch it right now.
