Critically and financially, The Last Wish was recieved rather well; but just because if they go for Shrek 5, it doesn't mean anything's on the table after that in terms of expanding.
I'd cool the jets till Shrek 5 proves itself that the Shrek "mainline" brand has the ability to stick out. But I would like to ask, couldn't this just of been posted in the Puss in Boots thread?
