Unfortunately the show has been on a steady decline since Oum died. While I don't 100% believe Shane, and think his "wife" is complete nutter, I do think they've changed his vision. A project like this is going to have to change, even well thought outlines will have major revisions as you actually flesh out events. But I think they have given in to the shippers with Bumblebee, and majorly pumped the brakes on the storyline to maximize years on their cash cow. They'll inevitably have to speed up and rush to the finish after it starts failing.
