I think that's exactly how you're supposed to feel, and I'm quite confident it was deliberate from the casting/directing side.

Spoiler!

When you see Kylo for the very first time, it seems like he's already an established Sith, a real, unwavering bad ass. As the movie progresses, you start seeing chinks in his armor and by the time you see him take off his mask, he's essentially fully exposed. You find that he's nothing but a spoiled, bratty, vulnerable nerd. I think the way they developed his character was amazing.
