this stoners-meet-government-assassins mashup is as meandering and paranoid as a guy toking up in front of City Hall. Sometimes that's amusing, but most of the time it's tiring
the movie is a fun mess, and Eisenberg and Stewart, who last costarred in the understated 2009 indie Adventureland, make for unlikely but endearing (anti-)heroes; they're Bonnie and Clyde with a water bong, an extra-high body count
the film has a lot going for it but, like a fridge-clearing omelet prepared after too many bong hits, it can't manage to cook all these goodies into a palatable whole
a high-concept movie with marketable names that nonetheless gets shoved into theaters late in the summer before reviews and bad word-of-mouth quietly send it off into oblivion
"American Ultra" hopes to leave you both shellshocked and blissfully stoned, but as a perfect storm of aggressively repulsive choices, it's a queasy bad trip worth avoiding at all costs
