Man! those were the days of my early like for Nickelodeon. It was around 1993 when got cable and spent hours watching this particular channel.
"Clarissa Explains it All" was one of the most popular shows because most puberts felt identified with Clarissa. To be honest with you, I had a huge crush on Melissa Joan Hart and that's why I watched the show. She was the most perfect female blonde on t.v.!
Then, on the entertainment factor, the show had it all. It was good for kids, puberts, and probably some teens.
I can't really determine if the show could fit in today's standards for teenage fun. The show was somewhat cheesy, naive, and felt uncomfortable while trying to add a moral message when Clarissa solved her "situations". It's a new generation people!
Still, I had fond memories towards this one.
