What upgrades? The only upgrades I saw happened in the final season. Animated also had the terrible practice of introducing a character then dropping him off the face of the Earth until they came back for their next episode. Soundwave, for example. Why bother buying his toy if he pops up in one episode? He pops up after two seasons near the end, but that's still weak writing. Sari was a plot device more or less, and didn't do anything worthwild until the final season. I think the main problem with Animated was that nothing realy mattered until the third season. They started doing upgrades (like for Prowl and Sari), kept the characters around, and other stuff. But before the final season, they didn't. If the kids in Unicron Trilogy were teen fufillment, then I'll argue Sari was kid fufillment. Especially during the first two seasons. I think a better example to use would be Beast Wars. No (fully developed) humans, permenate upgrades throughout the series, death that drives the character development and story in addition to making room to sell new toys. Beast Wars mashed selling toys and story wonderfully, and is probably the best toy commercial I've seen. Though that being said, Beast Wars is the only good American one I've seen, the rest are in the vein of He-man and Chaotic, and My Little Ponies. Japan just has more to pick from in the end.
