Finally got around to watching the new show recently and to answer your question,
@mr3urious, yes, they did keep the "Producer Says" segment. As for the rest of the show, it's a pretty standard show for smaller kids. It's not amazing, but it's not bad. It doesn't quite have as much personality or humor as the original, but it's nothing that would make most original fans angry. It has basically the essence of the original, and the characters are more or less the same. Kate McKinnon is charming as the new Ms. Frizzle. One thing i'm rather happy about, you guys may remember me saying how Phoebe was totally useless and rarely contributed to anything besides spouting her useless catchphrase ("In my old school..."), well they completely get rid of her in this version in favor of a somewhat similar, but actually useful new character Jyoti.
Tim, on the other hand (y'know, mandatory black kid) still does absolutely
nothing. I mean, he is still so bland and he barely has any lines! In fact, I think he has even fewer lines than he did in the original, which is saying a lot. Also, he has a curly fro now (?), and his skin tone is lighter;Did Tim somehow become mixed race since the 90s??? Ms. Frizzle's class is effed up, man, messing with people's biology and ancestry. She needs to be locked up.
