It's hard to be objective when I dislike the concept of Windblade... another "Drift" that suddenly becomes a prominent character who is made to look like they were always there... when there could be other pre-existing characters to bring to centre-stage as a major character. It just feels so forced, and if you aren't yet familiar with her or her standard character traits, it makes you focus more on her character just to try to understand what is going on (which in itself is confusing in this cartoon).
In other words, any episode that has her featured in it (and this one has her as the primary character), I'm just not interested enough to like it because it doesn't feature characters that have always been a part of Gen1, that I do know and care about.

As for Optimus, the animators don't do motion very well, with him moving like a zombie mannequin... especially when he was first backing away from Windblade at the start. That just looked really terrible.
And his voice reminded me of the Autobot leader from within the Matrix in the Hate Plague episode... it was way too digitised.

This series had better start throwing in some (credible) action or it is going to lose everyone before it ever gets to a climactic final conclusion.
