Given that it's supposed to be the first part of a new series/movie/whatever thats a given.
Uh, how is SC not anime? It's animated by the same people that do most Japanese productions (hint: they're not Japanese). Furthermore, there's plenty of stuff that comes out of Japan that looks like utter garbage so that's a ridicuous argument.
Oh right, if it's not Japanese it's not good.
Uh, wasn't Macross Plus kinda well known for breaking away from the hand-drawn norm of anime of the day? What with all the CG and all...
Sentinels designs appeared in Zillion because Tatsunoko had put a lot of effort into designing all sorts of crap for The Sentinels and when the series went bust they had a lot of unused designs they needed to put to use. Had nothing to do with a Japanese conspiracy of stealing Sentinels for their own use.
Although the Japanese working on The Sentinels WE'RE against using the characters from the Macross Saga, there were different reasons. One was that if word got out there was some kind of Macross sequel Japanese fans would go crazy. That's why the Macross characters look SO different in The Sentinels. The second reason is that the general practice in Japanese animation is to use new characters for new series...
