I'm actually a fan of the flash system (one of the few), but only for the clean design that can be imparted, though usually they are horrid, bloated things.

One example of a flash site I like: http://www.maraini.com/index.htm

Flash is definitely not needed at all, though.

One example of an html site I really enjoy--very simplistic and to the point: http://www.scootermagruder.com/index.html
