KILLING SEASON: deadly dull

Presumably the intention of casting two heavyweight - and expensive - Hollywood stars in a film is to double the number of bums on seats. It creates an event, attracting not only fans of each of the two stars but also those interested in seeing the two working together - in this case for the first time.
Remember how much extra publicity the pairing of Robert De Niro and Al Pacino generated for 'Heat'?
Well, KILLING SEASON is nothing like 'Heat.' It doesn't even rise to the level of 'Righteous Kill'

which was the disastrous attempt to capitalize on the buzz generated by 'Heat' by reuniting De Niro and Pacino and putting them together in practically every scene. It was just unfortunate that every scene stank.
KILLING SEASON gives us the first on-screen pairing of De Niro and John Travolta but completely fails to capitalize on their presence. The film is a total non-event, and the only thing that'll keep you from nodding off is the grating sound of Travolta's ridiculous attempt at a Serbian accent.
But, in retrospect, I really shouldn't have been surprised.
DeNiro's been turning in cruise and collect performances for years (with the notable exception of last year's 'Silver Linings Playbook') while Travolta's been milking his 'Pulp Fiction' rebirth for even longer (with the notable exception of 'Hairspray').
Rarely have two such big names contributed so little to a film, other than the further tarnishing of their reputation.
