Tom Cruise can’t be replaceable. He did his best. I am impressed. Christopher Mcquarrie, The director of the movie directed so nicely that we can watch some modern effect also. You should watch it on the movie theater. If you watch on hall then you can enjoy its sound effects, all actions, performance.
If you are still thinking to watch, please don’t waste your time to think too much, Go and watch. Otherwise You will miss it.
