Analysing fantasy, I find, is like a meal with salt. Something that makes no sense whatsoever, colossal plot holes and the like are like a food without flavour, many can do without the flavour just because they have nothing better on hand. Overanalysing something can destroy the point of the fantasy since you're trying to make it a reality, which is like piling on the salt...you ruin your own experience by messing with the whole concept
Getting enough analysis, and a suitable plot, can make the whole experience better; a perfect dish
