Oh i thought you was talking about the jumpsuits, but yeah i didn't think about that, theres just so much stuff in this movie thats unexplained and seems impossible, i didn't hate the movie but theres just so much stuff like this that theres no explanation for.
To me its a very bad job on the writers part to have all this stuff in there and provide no explanation for it, you might as well have had a alien walking around in the background, why not? you don't explain any of this other stuff. Its easy to just put down on paper something like them all having matching clothing to their counterparts, but if you can't explain why then it shouldn't be in there.
I get not needing everything explained and letting some stuff be a mystery, but simple shit like them all having matching clothing to their counterparts should be explained, cause you know what it tells me when it isn't? it tells me the writer couldn't think of any plausible explanation so he just left it unexplained. Which again is a bad job of writing and its lazy.
