Horrible watch, won't watch again, and do not recommend.
I'm not a big fan of Ben Stiller (most of the time), and definitely not Vince Vaughn. I like Jonah Hill, but this is after he found some range and before he learned to control it, intense doesn't not equate funny. I thought Richard Ayoade would save it, but he just stood by and watched the train wreck happen. I do chuckle a bit thinking of him asking the other guys if this is stuff Americans find funny.
This has a great premise, average joes find alien invaders, so good in fact, it's basically a trope, but the way this presents it feels like they tried to steal it from "Laser Team" and then legally distinct it from that property.
Long story short, there just isn't a lot of value in the movie. It's not that funny, it is basically a huge commercial for Costco and some other obvious brands. There is so much money poured into something that feels like a waste.
Don't get me wrong, it's done by professionals, it looks great, even if I don't like the Xenos design, and there is a decent script at the core of this. There is just an overall fail of execution, and lack of interesting characters and story.
You should go watch "The World's End" instead.
