good idea / bad idea

I saw the trailer for Clerks II - it looks funny enough, but man that is really laying it on the line to actually use the sequel name rather than just another title with some (or all) of the same characters. Clerks is a classic - although I am probably the only person between 18 and 35 who hasn't seen it all the way through.

Why risk such a big rep? Well, obviously the first reason is dollars. The second reason could be that it really is worthy - see also Back to the Future II.
