Decent movie for what it is. It moves along well and works. However I personally tired of the over and over again, unlikely, “coincidence of”” each person being saved at the LAST second, before death or being eaten. That became a bit hard to fit the believable. That ant the fact that in very very large complex, our separated people, “ran into” or found one another,
“Just in time.”… Overall though, like I said above, good movie, I did like it for what it is.
