Definitely, a good thriller with loads of suspense elements and the twist in the climax was although predictable was still convincing enough and the confusion that stayed throughout the film of guessing the protagonist & antagonist was engaging enough to keep you guessing till the very end and even though if you would've predicted it, the film still convinces by mixing it up with a different group of people also doing the same thing, it was a definitely a decent enough twist that convinces with your time spent well on the guessing part + some more twists.
Although the film travels & tries to keep us engaged, it still feels like being dragged in some portions and the content itself was very old, nothing new was presented here except the screenplay part which kept us guessing, still, there could've been much more improvements done to make the overall film even better but that opportunity was missed.
