If you keep an open mind, yes.
It isn't written by Christians, so it's not entirely Biblically accurate, and whether or not Christ is God is kind of left ambiguous. It can go either way, depending on what you believe yourself. I know Christians who like it, but I also know Atheists who enjoy it. It's interesting because it doesn't portray Judas as evil, more like a guy who ended up doing something terrible.
The music is (mostly) really good. It's 70's style rock music.
Here's Judas' first song
Again, it's from Judas' point of view (and he is wrong. He completely misses the point of Jesus, which is what makes his story so tragic).
I'm babbling but what I like about it is that Jesus is played as very human. I guess, as someone who isn't sure of what she believes, it makes him more real to me.
However, I'll bet you anything your parents wouldn't approve of it.
