I'm only born in 1994, so Saved By The Bell was a bit before my time, however I used to watch it on Nickelodeon as a kid and vaguely remember the college years from ages ago. Now I'm in uni I figured it would be interesting to revisit the whole Saved the Bell thing, so I've recently watched more or less every episode from start to finish, and I can see why you might say this is a bit stupid. For people that watched Saved By The Bell, its a nice continuation so you see how the characters grow up, and gives you a bit more of the same. And true, the issues raised are similar, and at times I'm like "why would he go through the same thing again!!!" but it didn't bother me too much. Overall I'd say its nice for people who watched the original series, but I doubt it would hold its own as a stand alone programme.
