Every day I wish Blockbuster was still a thing. Going to the store, spending 45 mins arguing with your family about which movie to watch, spending every penny in your bank account on popcorn and ice cream...That shit was THE BEST.
This isn't that, but it's close. Netflix has added a new feature where you, your friends and your family can choose a movie to watch together, then stream it at the exact same time.
Not sure what happens if someone needs to go to the bathroom though. Funnily enough that wasn't answered in their FAQ.
