Non-original projects vs. Original projects

I have noticed that projects at LEGO Ideas that are based off of some form of media initially get a boost of supporters from the fan community, but then after the fan base on LEGO Ideas it takes a long time if ever to reach 10K votes. If you look at the approved ideas you will notice that most of them are original creations, or non-original creations that are popular. This is why I suggest that if you want an idea to reach 10k votes, to post an original idea, unless your non-original idea is extremely popular.
