Sigh.
I haven't fully seen anything from this generation, but, in memory of G4, I still have followed it, reading about news, plot progress and fans' discussions and reactions to all this.
And if this info is true, then I have to say I am not surprised, and - I am not sorry about these news.
I can call a hundred problems I personally found in this generation, and I still think the main problem of this generation was parasitiziting on glory and worldbuilding of G4. And even this was made in the worst possible way and didn't save the show. If they made a separate universe, and have kept serious themes they tried to bring up in starter movie, it would work, imo.
Only thing that bugs me is the show doesn't seem to get the ending in ANY form, what is bad for any fiction product, even G5. Even if creators decided to cut their initial plans, then they should end the show SOMEHOW, to make it completed.
