Authors spend lots of time building up worlds that, at least on the first few visits, can seem pretty magical. But there's a flipside to that coin.
Sure, Narnia has magic doorways and talking deer, but the best candy available there is apparently Turkish Delight.

The Marvel cinematic universe has the technological ability to build smart exoskeletons, but it also has sentient killer robots.
Tell us in the comments about which fictional world, while perhaps fun for a visit, would get old to live in pretty fast — and why.
