Can’t stop the signal
After rewatching the show last year, I've realised that season 3 holds up super-well, even MMC. At the time I liked S3 much better than S2, but even during S4 considered it one of the lesser seasons. These days I'd consider it one of my favourite seasons. Yes I still believe that MMC should've been a two-parter, but for what it is I really enjoy it.
I know that due to the show ending, gen 4.5, and the pandemic, has ramped up the re-evaluation of the show and especially earlier seasons and controversial episodes, but I do wonder how many of the people who are now celebrating everything up to season 7/8/9 (more or less) have actually gone back and rewatched the earlier seasons. I'm not diminishing their nostalgia for "the good times," but that it's one thing to go "Yeah I didn't particularly care for 'x' at the time, but now that I about it, it's pretty good" and actually rewatching it to see how you feel about 'x' now. I did that, and is why I like MMC and especially MMMystery on the Friendship Express a lot better now than I did at the time.
It'll be interesting to see how my views on the likes of the rest of season 4 and especially Rainbow Rocks hold up upon rewatching them…
