Romero sticks to the usual formula.
In terms of Romero's entire 'Dead' series, 'Survival' is certainly not going to be the most memorable. I admire George for still cranking out good horror and gore with minimal aid from computer / digital animation. And yes there are a few scenes in this one that'll make you jump.
But the overall problem w/ 'Survival' is it's weak story line that just gets more and more absurd as it goes on...absurd even for a film about flesh-eating zombies...lol
Not a great zombie flick but I'd certainly watch it again before I'd sit through that titanically bad 'Dawn Of The Dead' remake from '04.
