I don't see a lot of difference between scarfing up incomplete, cliffhangered novel-length episodes every 4 years or so, and reading short, incomplete episodes every week or so. The vast majority of your time in any kind of installment plan story is always spent waiting for the next installment.
So if I can't get true stand-alone novels in my preferred SFF genre... I'll take the serial format that puts new stuff in my hands more frequently.
