I don't think RLT necessarily has no value; if it starts dialogue that's valuable in and of itself, and I don't think Keshavarz considers it unmitigated evil or anything. :) Personally, I'm unlikely to read it at this point, as I'd rather go read the other books she talked about in Jasmine and Stars. It's likely that what you take from it depends in part on what you had in your head going in.
