Would a D & D blitz be a good way to introduce new players to D & D?

Some time ago, I was shown a new way to play D & D, where the DM gives you a random character and lets you play a quick game of D & D. I've used blitz tricks to help more experienced players cope with more challenging challenges and to help me become a better DM. I was wondering if using a blitz to teach new players how to play D & D would really help them or it would complicate things. Personally, I think it would be nice because it's easy to install.
