I don't care for the multiple jackpot shots, and have wondered if others felt the same.
A jackpot used to really 'mean' something. You'd work up to it, score it and then have to work (sometimes even harder) to get it again. It just doesn't feel right to me when playing a game that gives repeated call outs for 'jackpot!', 'double jackpot', Super duper jackpot!', 'quintuple jackpot with ice cream on top!'

Maybe I'm just old fashioned, but the term 'jackpot' should be saved for something really special.
