Pros:
Music 9/10 (Lalo Schifrin's music gives more tense especially at the action scenes)
Scenery 10/10 (Meteora are really breathtaking... we should see more often this place in movies)
James Coburn 8/10 (Cool as always... Classic Coburn)
Cons:
Scenario: 4/10 (Plain scenario, no surprises... ok it's a 70's scenario but still they could have work it more... I mean James Coburn fighting Leftist terrorists on Meteora?..)
Direction 5/10 (Hickox isn't Hitchcock, that's for sure... aerial shootings though where actually good)
Conclusion: It's a classic 70's action movie. If you decide to spend your time to watch it you won't regret it. But the next morning you'll not remember a lot. Maybe only the stunning scenery of Meteora. It's 7/10 by me.
