Most movie remakes anger me greatly. Movies are the kind of thing you can put onto new formats easily and still appreciate what they meant. Movies that have to do with key current events that no longer apply can be updated to apply to a new generation, but outside of that I feel they are just wasted space in theaters. For example, the Friday the 13th and Halloween remakes are useless, but The Day the Earth Stood Still having a new pro-not-fucking-up-the-planet outlook instead of the Cold War is more up to date.
Game remakes are almost NECCESSARY because many of the OLDER systems die out and are impossible to retrieve. For example, I never owned an NES, so the Virtual Console releases of things (or better yet, the portable console remakes) are a blessing! I never played Chrono Trigger, and the control scheme changes in the remake made it feel like a MODERN game to me, not even a remake, to the point that I could finish it in just a few days.
