If you're a Robotech fan, you need this film, no questions asked.
If you're into anime or animation in general, however... Sentinels is the result of the abortive attempt by Harmony Gold to create a series that would fit into the "Robotech Universe" (consisting of altered series Super Dimensional Fortress Macross, Super Dimensional Cavalry Southern Cross, and Genesis Climber Mospeada). In the original series, 3 successive generations of wars are shown; the first generation (Macross) being the most popular, and the second (Southern Cross/Masters) the least. The need was felt to show the continued adventures of the first generation characters over the time-span of the second, and leading into the third, as the original series made continuous mention of the "return" of the original characters, but was never shown. Confused yet?
Animation in Japan began, with "aged" versions of Rick Hunter, Lisa Hayes, and other protagonists from the Macross story arc, and stories designed by Harmony Gold. Financial backing was given by Matchbox Toys, who were manufacturing American toys based on the Robotech series. Unfortunately, Matchbox's finances weren't up to the strain, and the Robotech "fad" seemed to be tapering off, so production was halted after fewer than 4 of the proposed 85 or so episodes were animated.
Harmony Gold didn't want to completely write off the whole thing, so they stitched together the completed animation.
Is it worth it? Only if you're a Robotech fan. It's great seeing Rick and Lisa again... but the animation really isn't up to the par of the original Macross, the story line is very sketchy and incomplete (by necessity, of course), the voice acting is worse than the original. Streamline/Orion have been selling this as straight anime, and most people accept it as such, but I feel that this is misleading, and may reflect negatively upon newcomers' opinions of anime. It's really no different than any other "American" cartoon- story and character direction came from America, and the animation seemed to have been done half-heartedly by Japanese studios.
