Big World Big Adventures is frustratingly bad. Both the movie and seasons 22, 23, and 24 that followed it. It is _legitimately_ bad. Because it is _legitimately_ why the series ended.
The target audience wasn't satisfied because this A: this content already exists (i.e. Paw Patrol, Minions, etc.), and B: the show was lazily marketed because it was barely aired on Nick Jr. or released on DVD or streaming until almost a year after it came out.
The fans (myself included) _definitely_ weren't happy because they show they've grown up with went from being a down-to-earth, easygoing story to loud, campy, neon-colored brainrot.
BWBA (both the movie and seasons 22-24) ranks low for me because loses both of its intended audiences because of both its poor marketing and outlandishly hard-to-watch execution.
The part that hurts the most: It could've worked perfectly.
Friendly reminder: Thomas The Tank Engine & Friends is, and always has been a show about trains, right? Right.
So, if Thomas is travelling the world, we could learn about China's bullet trains, or India's mountain railways. But instead, we pretty much learn the stereotypical aspects of each countries. I'd _much_ rather learn about the different railways that exist. And _that_ would've been the show's niche. Simply put, the show's niche is gone. And because of that, alongside poor sales and criticism, the show has ended.
In summary, BWBA fails in almost every way, and I don't recommend it. In my eyes, Season 21 is where the series ended.
