I believe people will like and relate to Legos in general. So many of us played with them as children. And some adults still do.
I think people may have trouble with the story when I mix in the time, clocks element. The two subjects will need to be made to work together in a compelling way. That is one of my challenges.
I think they way I can aliviate this issue is to make the story compelling. Also by using coherent writing and a clear overall message.
