For example, I'm pretty sure that

Aren't to be taken too seriously
Edge of Tomorrow came out in 2014, a scant 3 years ago.
Interstellar came out in 2014, a scant 3 years ago.
Looper came out in 2012. It wasn't as big as the other ones I've mentioned, but its box office returns were 6x its production budget (which is much better than some of the bigger names above).
Gravity, 2013, might be argued to not be sci-fi but science fact, but presuming we can reasonably call it Sci fi, it did pretty well, bringing in about $723M in revenues.
Inception, 2011, made approximately 5.5x its budget and brought in around $826M, which is successful by most people's account
District 9, 2009, brought in only around $210M, but only cost around $30M or so, so a 7x multiplier, and hugely popular

Now, it's likely -- this being Slashdot -- that someone will argue that some/all of these movies aren't good, or particularly original. That's fine. The original claim was "no successful Sci-fi movies in the last decade who aren't remakes, [s|pr]equel, or spin-offs. None of these movies are that.
I have a decent-sized living room; but it's also got pretty big windows facing a valley, so darkness is a pretty hard thing to accomplish.
Also? Kids. I've got a 22 month old kid at home. I can either wait until he's asleep (at which point I can't have the sound at a level commensurate with moviegoing experience) or do it when he's awake, at which point, of course, we're limited to what's appropriate for 22 month old kids.
It's far simpler to hire a babysitter and go on a date with my spouse to the movies.
