8. Dont Ruin A Classic
A lot of people might scoff at this one, as every time a sequel or reboot of a classic film is mentioned, at least one person will say This is a different film, how will it ruin the original?" But lets take another franchise: American Pie. The first two are some of the best comedy films of their generation, but since then there have been several straight-to-DVD releases that use the American Pie name (Band Camp, Book of Love) that have been absolutely awful. Now, when someone mentions American Pie, you will end up remembering these films and how terrible they are. Sure, the originals are still great, but the memory of the other films will taint your view of the overall franchise. This could be the case with Ghostbusters 3, because if the new film ends up being awful, every time you think about or watch the originals that bad memory of the third will still linger in your head.
