* An Arcee who ACTUALLY DOES THINGS! And she's not pink!
* A not-so-doofy Bulkhead.
* The voice cast in general - and IMO Welker's new Megatron voice is friggin' awesome; it blows his G1 Megatron voice clean out of the water.
* The new TF designs - they evoke the detailed nature of the movie style and yet aren't as overdone.
* Decent CGI. Not great, certainly not 'Clone Wars' level, but leaps and bounds above the last couple TF series to employ CGI.
* Two episodes in, and already one Autobot's been kacked. That's harsh.
* The return of space bridges, at least in some form.
* The 'Blood of Unicron'. That just sounds so much cooler than 'Dark Energon'.
* Soundwave! Wish he had an actual voice, although laying in the classic vocoder effect over his 'playback' is pretty nifty - that's the kind of fanservice I like: subtle and not slathering it on.
* THE SINGLE MOST AWESOME VERSION OF CLIFFJUMPER I HAVE EVER SEEN.
* The movie-esque music score.
* The mountain headquarters.
* The fact that Agent Fowler, at least so far, is being portrayed as a concerned and perhaps rightly agitated representative of his country's leadership as opposed to the stereotypical antagonistic bureaucratic tool like Agent Whatshisface from ROTF (I can't remember his name, I only ever saw ROTF once) - it'd be a bit too weird IMO to hear Winston Zeddemore acting like Walter Peck.
