The animation has improved significantly but if the style of it (3D animation, computer generated, the like) isn't your thing, it will probably be difficult to be drawn in. If you are able to look past the cheesiness of the early episodes the writing gets steadily better and much darker as things go on.
What exactly do you mean "the look of it"? I'll give you that the slice-of-life animations are a little stiff, at least in the first season (haven't gotten around to the second or third yet, whoops), but the combat scenes are top tier. If you like over-the-top action scenes with crazy as **** weapons and moves like I do, at least.
Why is exposing Pyrrha's semblance a big deal? Is the Polarity Semblance rare/a big deal? I know it's super strong, but so it Weiss and her runes/summoning, Rwby and her speed, etc.
It's the secret behind her skill, and it's the reason she's considered the top fighter in her age group. If people find out about it, they'll know why she seems untouchable in combat: she's literally untouchable in combat.
Worst case, people will actually accuse Beacon of cheating in the tournament by putting in somebody who can stop any weapon.
That's pretty chill for a worst case scenario. Pretty sure Penny will die, people will freak and Grimm will show up. Which is really sad. Look at how happy that robot is!
I can't really see them killing Penny off permanently, but I guess you never know. I figure Pyrrha would figure out something's up when she makes contact with Penny and realizes that she is entirely metal.
It's pretty good. But some animations are pretty stiff since it is a pretty low budget. Also the creator of the show died last year. He is the reason why the fighting looks awesome in the show.
