Realistic in the effect and unrealistic in the plot and what the characters have to do

Rating: 5/10 (18 July 2017)

Life (2017)
A meld of "Aliens" and "Gravity," with strengths of neither. The underlying point here was to make this idea—a Mars life form discovered and in quarantine on the Space Station—seem possible. And the big question: then what?
But they make it impossible. There are moments of reasonable acting and believable responses, but mostly it's exaggerated and sometimes just plain stupid. That is, the characters do really stupid things, given the situation. "Gravity, for all its visual excess, was also weirdly down to earth and believable. "Aliens" made no pretense of truth, of course, but it had actors that had intensity and depth. "Life" it a parade of obvious clichés in the booming space movie business.
It's not impossible to watch. There are well orchestrated effects, and a feeling of weightlessness that's good. The acting is a mixed bag (and the leading name on the list, Hiroyuki Sanada, is just one of the crew, nothing notable). I think it gets passable ratings because it's kind of fun, and if you don't really care about the feasibility of this life form in this manner, and you don't care if the plot is absurdly unrealistic, then go for the ride.
And for the great, improbable twist at the end.
