I think the 'paradox' here is (as with Cloverfield lane) the appendage of 'Cloverfield' to these films when they have so little similarity to the original except a backdrop story which features little.
Anyway this one starts out reasonably well and gets better as it goes along reaching a point midway where you think this is well good. Then it all turns to shit, the storyline gets lazy, too much has no conclusion or apparent reason why it has anything to do with anything.
The worst of the laziness comes in the main characters storyline, she says she needs to do something when clearly even a kid could tell her 'no you don't you can just........' anyway I won't spoil it in case you watch it.
Maybe I've done it a disservice, I've seen a lot worse and it is good 'til half way so it's worth a watch just for that but don't be expecting too much from the ending or breaking any other plans you might have, just to watch it.
