Ideas on how to improve the ending
Once Michelle escapes from Howard, the movie's tension is gone, so you've gotta wrap it up fast.
Michelle sees the birds, takes off her mask, breathes in deeply, and we think that everything's fine.
Then she sees an alien ship off in the distance, and some jet fighters fly overhead to bomb it.
She drives off in Leslie's car, turns on the radio and hears the transmission, and makes her decision to help people in Houston. Roll credits.
None of that Molotov cocktail nonsense.
Any other ideas on how you'd improve the ending?
