I also saw Clerks II this weekend and thought it was pretty good...better than I expected at least.
By the way, for the frequent movie goers out there, we invested in a book of "corporate event" tickets. It cost $250 but reduces the price of each individual movie by almost 50% (in our case, our theatre is $10.50 a ticket, and this reduces it to $5.50, plus we got some extras like some free popcorn and drinks). I've found it well worth it.
