Read:** Time Travel Movies Are Garbage**Time travel is complicated and probably best left to people like Doc Brown or Rick, but let's see if we can parse this out: Today is October 21, 2015, which is the day in Back to the Future II that Marty McFly arrives from 1985 after Doc rolls up in his Mr. Fusion-modded Delorean. So far, so good.Marty, as you all remember, had just spent a few weeks in the 1950s, where he narrowly avoided banging his mom and effectively changed the course of history and transformed his family from a bunch of drunk wimps into paragons of 1980s culture straight out of The Big Chill.But before Marty had a chance to check out how his paradox-riddled foray into the past has changed the present (could Goldie Wilson be in the White House by 1985 after getting that early confidence boost from Marty?), he and Doc were racing to 2015 to continue to fuck the fragile space-time continuum faster than the Terminator movies.For those of us who had to suffer the indomitable slog through the normal, day-to-day realities of the 90s and 00s, we've finally caught up to Doc and Marty's vibrant, Cubs-and-hoverboard-filled 2015. We may even get some self-lacing Nikes today, if we're lucky.Marty won't be showing up until this evening, so we still have a few hours to prepare for the man's arrival—time to get your Pinheads cover band together.
