Is 07 Ghost worth watching?

I would say, yes it is worth watching.

It's about a boy named Teito Klein. As far back as he can remember he's been a battle slave, before he came into the military.
But recently he has been having strange dreams that are connected to his past. Soon he has to escape the military, and discover who he really is.

o something like that. I'm sorry, I don't explain things very well.
Just watch the first few episodes and see if tu like them.

Hope this helps. :)
