Does no one remember how shit and shallow Darth Maul or Dooku were or what
How could I forget Darth Maul? He's my favorite Star Wars villain!
He was very exciting on screen, had a memorable look, but he lacked any real depth to his story in the movie. Which is one thing I've heard people complain about with Snoke. I'd say that's true of many of the villains.
But that's just the thing. Maul was awesome and he didn't even need a backstory or any sort of motivation.
