Nostalgia is a funny thing. It can devour you, if you're not careful. One can lose oneself in it. Nostalgia can be a useful tool for remembrance, but it can also be deceptive. We can learn to love a past that perhaps doesn't always deserve the affection. This is especially true if it's a past we didn't experience. But even our own past can play tricks on us. Best, then, to take only small dips in the nostalgia pool, eh? The aforementioned thoughts regarding nostalgia are what developed from a simple airing of the 1985 classic movie Back to the Future on TV over the weekend. For the uninitiated, the film features teenager Marty McFly going back in time thirty years, to 1955, and trying to make sure his parents get together so that the family he knows and loves will be there when gets back to 1985. It's a great bit of cinema, and I clearly remember seeing it at the old Thunderbird Theater with my mom back when it came out.
