The show is not bad, but I can' say it's 100 % good.
Though the premise is good, in my opinion it has several flaws: lead female character is really pretty but with no backbone at all (which I find really annoying), lead male character is a jerk and I can't stand him nor I understand why on earth she's into him. Finally, the plot drags itself out too much.
Acting is average, too.
Overall, good intentions, mediocre execution.

On a side note: why are there so many shows with characters affected by prosopagnosia?
