As a future teacher and a current sub, I gave Welcome Back Kotter high marks based on my bias. This show will actually get a lower rating from me based on how annoying most of the characters were. Plus, the principal only took interest in this select group of students. Belding had to be the worst principal in TV history. He wasn't funny, he added little to the show, and he stayed in the role for like 5 more years with the next two classes of Saved by the Bell. Dennis Haskins apparently has no shame nor any career.
I can't bag on the show too much, as it was pretty cool in its day and I have probably seen every episode multiple times due to the fact that it used to be on syndication on different channels 24 hours a day.
However, the plotlines were often extremely ludicrous. While shows shouldn't be held to a standard of having to be realistic, they should at least keep it within this world. The show about oil discovery at Bayside and the drive to refuse the millions upon millions of dollars was laughable. Number one, they are in California and won't be dsicovering oil anytime soon. Number two, the town and adminstration are NOT going to refuse tons of money because of a few snot nosed kids.
I digress however. It had its time in the sun....and it just really hasn't aged very well.
