Very poor, despite the presence of John Cusack and Samuel L. Jackson.
'Cell' is basically 'Land of the Dead' without the proper zombies, at least that's what this 2016 flick kept reminding me of. That George A. Romero film is good, this Tod Williams release is not. It's a mess throughout and lacks any tension, freshness or uniqueness.
Cusack and Jackson should be a good pairing, yet I don't even recall anything from their respective performances just minutes after watching. Both are capable of a lot better than this, especially Jackson. No-one sticks out behind that duo, though it's neat to see 'Prison Break' actor Stacy Keach involved.
One to avoid, I'd say.
