I suspect the cancellation was because the toys sank without a trace.
Not just toys. ViacomCBS even planned to make Prodigy theme park attractions.
ViacomCBS Reportedly Sees ‘Star Trek: Prodigy’ As Gateway To Toys And Theme Park Attractions
ViacomCBS sees Prodigy as “critical”
“Prodigy” was viewed by many as critical to the fate of the “Trek” franchise, as it’s the first bid to engage families — a path that can lead to ancillary products such as toys and theme park rides
I love how people praise Prodigy now
That people over 30+ praising the show is the problem. The show appealed to the wrong demographic.
And likely they realised it was watched by the same 40+ crowd as the rest of their Treks and not the young audience they were going for.
That is what happened.
I remember the interviews with Alex Kurtzman and the marketing headlines.
Alex Kurtzman even compared Prodigy to Star Wars.
Prodigy is for "younger kids" (Not just "kids", "younger kids").
The contradictions in this interview are astonishing
Star Trek: Prodigy will explain the franchise to total newcomers
“We wanted a bunch of new characters that knew nothing about Star Trek just like our young audience.” They meet Janeway via hologram at the end of the first episode.
Why should a young audience that knows nothing about Star Trek be interested in meeting Janeway?
Star Trek Prodigy is a quasi Voyager spin-off. Voyager 2.0.
Janeway became the public face of the show.
And if characters from a 90s TV show (Janeway, Chakotay) weren't enough, they added characters from the 80s, like Okona and Wesley, to the show.
And then they ended the show with the Picard Short Trek and the synth attack on Mars. And we all know how kid friendly Picard season one is.
After the introduction of the Borg in season 1, Trekmovie published a large article about Borg lore and the connection of the Borg to Voyager and Picard:
Dark ‘Star Trek: Prodigy’ Theory About Zero Connects The Borg From ‘Voyager’ To ‘Picard’ And Beyond
Not very newcomer friendly.
And whose bright idea was it to connect a show for young kids to shows from the 80s and 90s and to a violent and gory Picard season 1?
All this may be interesting for older fans, but not for young kids.
