Watched it all this morning, from the youtube link that Ultra Marginal posted up in the news topic, and was rather bored throughout almost all of it, and disappointed that it wasn't an improvement over their unexciting Combiner Wars mini-series.

If this had been released a year earlier, it would make more sense dragging out the Trypticon plot device.... which just dragged on and on and on and on... I ended up spending time on the computer, as I would have otherwise fallen asleep.

I understand the budget restraints when it comes to cast numbers, but this was a Titans Return cartoon, and we only had one Titanmaster. And if it wasn't for Hotrod/Rodimus and Windblade already carrying over from the last series, it would have just been four TR toys being featured (Trypticon, Fort Max, Perceptor, Overlord).
The least they could have done is have Optimus and Megatron in their TR forms, just to advertise their toys... if they were still available at retail.
