Paul Feig’s Jackpot! asks a strange question: what if a film combined the maddash comedy of 1963’s It's a Mad, Mad, Mad, Mad World with the gory dystopian free-for-all premise of The Purge? You’d get a weird action-comedy that’s more of a vehicle for Awkwafina and John Cena that’s occasionally very funny, until it’s not. I couldn’t help but think that a few years back, something like this might have had a chance of becoming a minor hit in theaters.
