I didn’t think I’d like this because it looked like Ground Hog Day rebooted as SF and, well, it starred Tom Cruise. My bad. I cut my writing teeth in the SF field, so I gave it a shot and am very glad I did. This is top-notch military sci-fi. Cruise and Emily Blunt deliver. Don’t try to think too much about the time shifting — it will break your brain. Don’t try to understand why alien HQ is beneath the Louvre either. Just go with it. Lots of action and scary aliens that are truly alien. FF=1
