Well, those are all the very reasons I don't go to the movies anymore, all aside from the rising costs. Why would I pay $8 plus for snack to sit in an uncomfortable, crowded theater when I got an HDTV at home and a heated leather recliner?
It's called atmosphere. At least when it comes to BIG blockbuster movies and good horror and comedies.
Sharing in the excitement/horror/laughs of a large audience of fans in real time as it unfolds on the screen is an experience you don't really get at home.
Everyone says they HATE when people talk during the movie, but have you ever been to a horror movie where they talk at the movie, and in a way that actually boost your enjoyment level?
Or to a comedy that you thought was kinda funny, but it was really that couple down the row somewhere that was cracking up that finally got you to just let the laughs out and just enjoy the stupidity for what it was.
All things that you usually only find in the theater.
And now that they finally upgraded those terrible seats in most theaters I go to, and allow you to pick your seat ahead of time, I actually enjoy the experience more. I don't mind paying an extra $2 a ticket to not only be comfortable, but not have to worry about where I'm gonna sit because I showed up 2 minutes before the movie started instead of 30 minutes before the previews. Time is money, and I'd rather spend a little more money to save myself the time. Not everyone feels the same way, but that's also why they still have plenty of theaters with old seats, cheap ticket prices, and probably smaller screens.
Deadpool being self-aware is the reason they could easily put him in the MCU "as-is"...but it's also the reason they can't.
It's gonna be hilarious to see him pop up eventually in random movies, be completely aware of everyone and whats going on, crack a joke, and all the MCU vets just trying to push past him like he's some mental ward escapee that getting in the way.
He could be a bridge between the rebooted X-Men and the MCU proper for all I care, but his integration as-is, needs to happen in some way or another.
