I was in the same boat as you. ASOIAF, Kingkiller, and the Gentleman Bastards (also a little Wheel of Time) for me caused me to set the following rules for myself on deciding what Fantasy to read:

-Only start series that are completed. -Only start series that are five books or less.

There were a couple exceptions for particular authors that I liked, but that's it.

Lately, I feel like I'm just depriving myself of reading good books, so I'm currently reading The Blacktongue Thief which is rhe only book for that out right now.
