This is another advertisement for the sci-fi genre. You can do anything. The special effects are as minimal as could be, its mainly silly people doing silly things. The director was there, a very funny guy. He could be a successful stand-up comedian.  He said he wanted to approach an alien invasion from the point of view of the people holed up in their apartments from the curfew while someone else actually dealt with the menace. “Sci-fi for the 99%” is how he put it. Brilliant. So, all the normal rules are suspended until we find out if everybody dies or what; and people do what they do in such a situation. For laughs.
