The list of negatives is...rather longer:
- The animation is really cut-rate. The characters don't move like robots -- in particular, their torsos flex and bend like a person wearing an Optimus Prime shirt. They also barely transform. It feels like they didn't bother to even make alt-mode character models for half the cast (Optimus, Elita, Wheeljack and Bumblebee escaping from the Decepticons by walking casually down the street instead of turning into cars is especially notable). And most of the ones that DO have alt-mode models will lunge off-screen or have the camera swing away when they transform because no one wanted to animate the actual transformation. Towards the end of the show we see a character ripped limb from limb and when they show her remains it's literally just her regular character model with the limbs deleted, seemingly undamaged otherwise. Overall, it looks like an average Xbox 360 cutscene.
- The voice acting is attrocious. I'm used to this being the saving grace of other terrible Transformers shows, but instead of hiring veterans on the franchise or newcomers with actual talent, they asked Mr. Burns to do the casting: "Get me his non-union Mexican Youtube equivalent!" Optimus Prime is voiced by some random 20something whose claim to fame is posting videos of him impersonating Peter Cullen, and he can't act AT ALL. He does a passable job of sounding like Prime's closing monologues in the Bay movies, but as soon as they ask him to show a bit of emotion, he stops sounding like Prime and starts sounding like an angry teenager. Megatron and Starscream are also voiced by G1 impersonators who aren't especially effective at emoting. They were obviously trying to emulate G1 Soundwave, but he sounds more like Microsoft Sam than Frank Welker. Almost everyone else was totally forgettable, except for the lady voicing Elita-1, whose actually really good performance feels wasted on a show like this.
- A lot of characters who got toys in the Siege line didn't show up at all. The Micromasters (aside from Ravage and Laserbeak) and Battlemasters were entirely absent. Sixgun, Brunt, Crosshairs, Apeface and Springer didn't appear either. Nor did any of the Selects or store-exclusive toys aside from Skywarp. That matters because they populated the background with lazy, mostly monochrome palate swaps to fill out so very many scenes. Based on what we see, the Autobot forces are about 75% Sideswipe and Cog, while the Decepticons are about 85% Starscream and Reflector. Having actual, unique characters in the background would have made so much difference. And since the show models were apparently based on the toy CAD models, it's not like they would have had to put in a ton of extra work to do it.
- The tone of the show is really weird. Given that it's based on "80s Nostalgia: The Toyline", you'd think that it would lean heavily on references to the 80s media. And they used slavishly G1 character designs and hired G1 impersonators to voice most of the main cast, which solidifies that impression. But the writers clearly didn't get the memo. The story is the identikit post-2007 movie "Find the Allspark!" quest that we've all seen a dozen times by now. Red Alert is written like Armada Red Alert so that Ratchet can essentially be a reformed IDW Brainstorm. Jetfire is basically Dinobot and so is Impactor (which really smothers the emotional impact of both). Bumblebee is an angry rebellious teenager, etc. etc. All of which are honestly fine but it's really weird to see that happening while the presentation is all but screaming "1984" at the top of its lungs from start to finish.
