Not great, not bad....
..and not better than 'Predators' and 'The Predator' too to marginal extent.
This could've been handled lot better. Lot of things could've been done differently and added some more thrills and action.
Firstly, the English speaking Tribes itself takes the movie's ancient premise aback and made it look artificial. They could've definitely made like 'Apacalypto' with native language dialogues & English sub-titles - that would've made it a lot natural & realistic.
They changed the Predator design especially the helmet and made it look raw and tribal. Good. Differentiation is always required. But there was very less of it we could see and explore. I don't even remember it's face after watching the movie last night. The focus was purely on Naru and it was too much.
Characters were bland. The French cavalries didn't have any special character to create some excitement. There were no surprises, very less tension and less threat.
The Action was good. The Predator Shield was too good. But nothing more memorable; rather lacking of any favorite moments.
A simple pop-corn entertainment, 5.5/10.
