So here's my comments:
- New Frizzel is kinda nice. I dig her spunky, still figuring this out attitude.She doesn't quite have that all-knowing aloof god attitude as her sister.
- I like that they kept old Frizzel on as a the phone call answerer.
- Phoebe has been replaced by the pajeet Jyoti, whose name no one seems to be able to pronounce right (I heard Jodi, Joti, and even Jeeyoti). She's a super tech wizard who built a robo little sister, and seems to be the new smart one.
- This has reduced D.A. to just being a numbers obsessed autist.
- Most catchphrases are gone, save for "according to my research (which is said way too many times in a row), and the usual "to the bus/bus do your stuff"
- Magic school bus is specifically called as such, it's no longer just "the bus". At one point when it's spewing out bricks, Jyoti asks where it's getting the sand/clay etc to make them, with the response being "it's magic just roll with it"
- A lot of the relative jokes kinda fall flat.
- Fiona makes a comment about a relative/friend who drowned in a river - that was pretty dark for the show
- A comment by Fiona seems to imply that she and her sister built the bus as a school project, though I feel like there was a joke in the old show depicting the bus as like an ancient greek trireme, implying it's been around for thousands of years.
- The pacing was weird. Each episode felt overly long, but with not a lot of actual learning content. Like the science was all rushed.
Overall I thought it was ok. Not great, but fun for a weird sort of nostalgia trip. Interested to see what they do with new seasons.
