Spoilers!
A time travel movie, that was not. The director has no idea how Time travel works. Ignoring all the political reasoning, this movie is only but flawed from any concept of time travel.
The guy chases a girl, supposedly this grand-daughter, who he sent into the past to kill people with poor radical ideas has a rift with the girl all the time she visits the past. Easy to have said, anticipate me and avoid! The science behing the connection with the moon is flawed. Everything with time travel is wrong.
A (supposedly) time travel movie is just a movie for dumb watchers! People with no knowledge of time travel or people watching their 1st time travel movie will probably like it, maybe!
