graham cracker crust is okay if it’s just on the bottom. is absolutely not necessary, though!
i agree with ‘bit o’tangy’; not overly so, though. and i like it thick/creamy (not dry). not too heavy though – don’t want to feel like i’ve got a lump in my stomach after eating a piece.
i’ve had some that were SO heavy, just 3-4 forkfuls was too much. yes, it tasted fantastic, just couldn’t finish the piece (and it wasn’t all that big, either).
the best pumpkin one i’ve had was at the cheesecake factory. and the reason was probably because they used fresh pumpkin (they only offer it in the fall). other places that i’ve had it at it was not in the fall, so, they had to have used canned pumpkin. good, yes. didn’t have that ‘extra’ that the cheesecake factory one had though.
