The problem I see with this episode is that the platinum era of the series, which comprises the first three seasons, is already starting to fade here. The first three seasons had a therapeutic value, which declined in the fourth, and by the fifth, it had disappeared entirely.
The plot now serves solely for humor, which is why some people complain that it has a simple plot. Honestly, there are episodes of The Simpsons much more valuable than this one; the only thing is that this episode has some very good humorous moments, a well-crafted villainous secondary character and the portrayal of Leonard Nimoy's character is very amusing here. However, the direction of the episode is not as masterful as in other episodes of the series.
