Very true. I read the Mistborn series and absolutely loved every minute of it, so I picked up The Way of Kings thinking I like Brandon Sanderson and it's a popular book of his. I didn't make it past the second chapter because the story demands I memorize dozens of ridiculous names, made-up words, magical objects, and fictional cities right off the bat.
Suspending disbelief is not the problem. The problem is when the author writes something so unbelievable that there's never a chance to suspend. It's all disbelief, all the time.
Again maybe I'm ruined by years of reading bad sci-fi and fantasy, maybe I would have been better off if I read it 20 years ago. But Snowcrash and The Way of Kings both start their story with all of the hallmarks of every awful book I've ever read.
I'm sure the durian fruit tastes great, but unfortunately I've smelled a dumpster before and now durian is ruined to me forever.
