Jimmy Fallon engendered a lot of good will during his time hosting Late Night with Jimmy Fallon, and it looks like that will carry over to his new gig hosting The Tonight Show.  It feels like a fresh start that has a good chance of luring a younger audience, or at least an audience that will likely tune in to check out clips the following morning.  For example, during last night's show, Fallon was welcomed by a string of cameos including Robert De Niro, Tina Fey, Seth Rogen, and most notably, Joan Rivers, who was banned by Johnny Carson from The Tonight Show in 1986.  Fallon also had a fun bit where he and Will Smith showed off the Evolution of Hip-Hop Dancing.
