Mobile Suit Zeta Gundam
Popular culture makes a habit of idealism and wish fulfillment - the happy ever after fairy tale ending - but we all know that even the most optimistic ending has the risk of a messy epilogue. The Great War led to the Treaty of Versailles which ultimately led to the Second World War...the aftermath of which was several decades of Cold War and proxy wars fought across the globe. You catch my drift. The elimination of a power player creates a vacuum and vacuums have to be filled. It is here that Mobile Suit Zeta Gundam picks up after the original ends with our heroes victorious. It is here that the series succeeds - in showing how micro-conflicts between persons can blow up into macro-conflicts on the battlefield, the messiness of war, the tangled mess of loyalties and alliances and how history is doomed to repeat itself. It finds itself caught up in the cyclical nature of tragedy in a similar fashion to how the Star Wars saga would some years later.
Where I think the series is less successful is where its away from the battlefield. As with every Tomino work I've seen, plot drives character rather than the other way around which I think is the biggest criticism I would have of him as a writer/director. Our protagonist, Kamille, is really no different at the end of the series than he is at the beginning. Even with characters that do have an 'arc' like Reccoa Londe, there doesn't seem to be adequate explanation as to the motivations for them to change. Female characters are particularly underserved, frequently being portrayed as being less capable pilots than their male counterparts or easily swayed by the allure of men. They are all, obviously, good with the kids as this series also has a couple of pre-schoolers on board as it is in no way child abuse to put toddlers at risk of death on a battlefield rather than dropping them off at a day care centre somewhere where they can be properly looked after. Because there has to be a convenient way of emphasising a character's femininity and motherly instinct.
Nevertheless, its successes outweigh its failures. The animation has improved from the original series as has the score. Tomino's pacing has improved from the original Mobile Suit Gundam and even from what I consider to be his overall masterpiece, Space Runaway Ideon - while I think that you can cut away at least a handful of episodes from those series and not lose anything of consequence, in Zeta there is relatively little filler. There's more consistent momentum and less of a 'battle of the week' feel.
I find the comment above regarding 'good vs evil' interesting, as I would say that Zeta - an early entry in the franchise - already does away with that concept quite thoroughly. There's a lot of grey.
