i agree with Mike, this was a palatable story with decent entertainment value. Not great, not very memorable, but certainly not facepalm-inducing.
Though if we consider that we tend to remember the great and the terrible, I suppose this episode does qualify as one of the most forgettable: one of the most average.
Fair enough. Sometimes we forget that providing serviceable entertainment is not that easy and get bent out of shape when we don't get life-changing or mind-altering experiences. Looking at fan productions gives you an idea of just how hard it must be to do a decent show on a weekly basis.
