When done WELL I can enjoy both. Some of it is upbringing; BEFORE I read Tolkien, I was exposed to WarCraft II (NOT WoW, old school WarCraft!).

Then, for tabletop RPGs, I cut my teeth on GURPS. Which was happy to let you have evil orcs, misunderstood orcs, etc.

There comes a point where the inversion of tropes starts becoming the norm and it gets more than a little tiresome. It's only funny if the norm remains the norm so you CAN invert it.
