My wife really doesn't like sci-fi movies, and I forced her to see it at a decent RPX theater when she came with me on a business trip. She actually really liked the movie and even told our kids (2 daughters, one in high school and the other half way through college) that they would like it too.
Definite purchase for us.
For those upset about it not having Dolby Atmos, just ask yourself... When will you, realistically, get Atmos in your home? If it is, now be honest with yourself, in the next year, then sure... Wait to buy this. If it is some time beyond that, which it really will be for most people that even end up with Atmos at home, then worry about Atmos tracks for movies a year or so from now, and get this and enjoy it now.
I am confident that the DTS-MA track will be amazing as is.
If you have an Atmos setup now, then what are you listening to in Atmos anyway? Then I guess I would wait for sure.
