I think the ending should be that John Goodman and that woman who smashed her head in the door worked together. That Goodman hang his keys easy to grab on purpose, quickly texted the woman who put some fake blood make up and die fake. When michelle almost escapes, John admits they abducted the previous girl because his own daughter died and they wanted to replace her with a Stockholm syndrome "new daughter". Michelle escapes and there are no aliens . The end.

I disagree, that kind of idea (the apparently bad or crazy guy being the good one in the end) has been already used in other things like the episode of the Twlight Zone 2002 called "chosen"or the film
Frailty
, or even Tucker and Dale Vs Evil? lol
I liked the ending of the film as it is, Goodman's character was right about the "invasion" but was a psycho-killer at the same time and he used the bunker to kill another girl in the past.

I agree the ending was the weak point. Your ending is a great alternative.

THIS!
would have been vastly superior to the weird ass ending that happened.
It just becomes a completely different movie. The ending is so disjointed and misplaced.

The ending i was hoping for did't include any aliens. Instead Howard would turn out to be a liar and have set everything up. Not sure how to explain the woman outside melting away, but in a flashback we could muster up something that Howard used a secret exit to unleash toxic stuff etc.
I would have liked that better.
This whole War of the worlds spin didnt do it for me.

It would be hard to make a worse one in all honesty.

This ending would have made the movie worth watching

@MeOnline I like it, that's a downbeat, Twilight Zone-ish ending. Unfortunately, movie studios generally don't like downer endings.

Yeah Goodman was so good at being bad in this. The whole time she was running from the monsters I was half expecting Howard to come out all burnt and chase her lol. When it became apparent she was just gonna battle a big ship/monster (and ridiculously defeat it), I was rolling my eyes. Great movie, ending aside.

That would have been a perfect ending to me

Excellent!

I would tweak your ending just slightly. Instead of waking up onboard and being experimented on, her shower curtain suit and plastic bottle mask fail (because c'mon, it's a flimsy shower curtain and plastic bottles literally held together by duct tape) and she dies in the cloud of poisonous green gas, choking and gasping and starting to get those skin burn wounds just like that woman she didn't let into the bunker.

Yes, that's pretty goodor just have it the same as it was shot up until she sees the alien ship and realises she just killed the guy who saved her life, and destroyed the bunker which was her only chance of survivalat which point the aliens, drawn to the bunker explosion, show up, abduct her and she wakes up having a whole bunch of really weird, nasty experiments carried out on hershe screamscredits roll.
Hitler was a dog person.

I like it a lot.
