It just wasn't very exciting to watch in my opinion. Admittedly I usually prefer a series that has some comedy in it now and then, which I did not see in the pilot. I'm not saying I think they rely on humor, I just think a show needs a sense of humor to be great like Andy Griffith, Freaks and Geeks, and one of the most notable recently is the Big Bang Theory.
To be fair, the pilot was more based on introducing the universe and the show's main characters.
There's some comedy after that. Lots of it.
It's not just that though. I also thought the main character was pretty dumb. Worse is that they let her attend this college right after being caught out in the city past curfew? This is ridiculous. Just a bunch of confusing storyline like "Why would this lead to THAT?" or something similar.
That's RWBY in a nutshell.
People have made a lot of theories about certain events, especially the reason why Ruby got hired at Beacon.
The answers to many of your questions will eventually be answered if you keep watching (assuming you want to, of course)
Then there's the music. I've heard two of the songs from the soundtrack, and it sounds like a buncha tryhards wrote the lyrics.
I can't say anything about that one.
I like the soundtrack, but if you don't, it's alright.
After all, not everyone can like a certain style.
So three strikes, you're out. RWBY is not for me.
Basing yourself out of only the first episode to make general opinion of a show isn't a great thing for any show, imo.
Try to watch a few more episodes and if you don't like it, then I'll respect that decision a lot more.
But if you don't want to, I can't force you.
