There is quote a lot of entertainment in most flights, especially new movies but it's still going to take the time. I watch the new movies, usually three, and we're still only about half way to the destination so sleeping comes next, as long as I can without missing a meal. then it's another 2 movies and we're usually there. The only real way you get lucky is if you are the only one in the three seats across, so you can stretch out, but that's been only a couple of times, as most seats are booked. Some more times you can have no one sitting next to you so you get a little more room.
