I don't know how to classify Transformers Animated just yet. Episodes have ranged from abysmal (Home is Where the Spark Is) to solid (Transform and Roll Out Part 1). It's still too early to tell how good the show will be in the long run, but Thrill of the Hunt shows that it at least has the POTENTIAL to stand alongside the original series and Beast Wars as an honest-to-Primus good Transformers series.
When I was a kid, we had GI Joe, a show which didn't exactly spend a lot of time focusing on the horrors of war. Indeed, it's rare to see mental scars handled the way they were in this episode, which focuses on Ratchet's post-traumatic stress disorder resulting from his capture and imprisonment during the Great War. In contrast to the original series' requisite battle-hardened codger, Kup, this Ratchet doesn't want to spend time spinning yarns about his adventure and heroism; he doesn't want to talk about the war at all. He gets flashbacks; he is haunted by the things he saw. It's awfully deep stuff for a children's cartoon, and handled in a very mature manner.
And as a bonus, it was good to hear Sue Blu reprising the role of Arcee some two decades later.
