Precisely. Even though Star Trek: TNG was a great series in its time, it turned me off the "planet of the week" formula.
Yeah, I don't mind a series running to a formula sometimes, but it does get ridiculous when they just rehash the same ideas over and over. When they do that, you know it's time they finished. The logic in some Star Trek episodes was poor, but when it was at its best, it was unbeatable. I think I remember that episode you mentioned, there were one or two that were very similar if I recall, and the transporter did seem to cure a lot of stuff. These days a lot more is expected from a series.
