It is reasonable to expect it to look something like the concept, not nothing like the concept. You trash the concept if the people reject it. This si clearly a "Plan B" design, and it is much less worthy of interest to me. And Lexus has a history of staying true to their concept's designs, and not throwing them away entirely.
If you want a cut-rate design, have at it. There is no good reason why they couldn't use the design of the concept and adjust the styling for production. It is unreasonable to expect the production car to look nothing like the concept, given Lexus' history, with the LC most recently.
This looks like just another luxury car, and after waiting 8 years, I think we deserve better. They pretty much told us last year to expect the best, and then they wimp out. Why go all in on the LC, and get all kinds of positive press for it, and then punk out here? Who was bashing the LF-FC Concept, in any way?
