Legend of the Galactic Heroes is one of the longest anime I know of, and the longest I have watched in it's entirety. It is a highly rated series and before tackling it I had yet to see a single poor review. Now I understand why. It seems only scifi junkies(such as ones who find themselves intruiged with star wars/Trek just on the merit they are in space) tend to complete the series, and others drop it so immediately it's not worth endowing with a review.
The general story is that two titanic forces are clashing in space while a third neutral party lies in the middle of it all. A basic set up for a fairly basic story which progresses little for the massive 110 episode length. The space battles which absolutely pollute the series are unacceptably poor. I understand it's an old/low budget series, but then why not shorten the battles, especially when the outcome is always so evident? The trend of the series is identifying opponent's of the main character by how stupid and narrow minded their ideals are and waiting for the main character to crush them. Moderately interesting political talk, evident opponent appears, long battle where they narrate how intelligent the main character(s) in the fight are, fight ends with some "impressive" tactical manuever, repeat. That is the series story, one which fancies itself as profound but never realizes it's ambition.
Bad, somewhat improves as the series goes on, however only the space battles are unbearable. The series is old and low budget, and the non-space moments would be passable if not accompanied with such a poor story. Space fights consist of the same looped footage of ugly ships blowing up in space, radars showing how the battle is going as a character narrates.
Nothing special, again though, space fighting hold even this category back a bit.
For a 110 episode series, it fails at creating interesting or believable characters. I must stress, one hundred and ten episodes and even the main characters of the series are weak. Compared to a series like Monster which is also long, it utterly crumbles. Main characters are intelligent, side ones are not and the actions of both are overwhelmingly predictable. The series also introduces COUNTLESS fluff characters, which are named(sometimes with a caption) and generally forgotten about/discarded. They could easily only have the names of slightly relevant characters pop up but they insist on naming every group of people who is introduced. Because of how much of a joke the main character's opponents are there is rarely any tension, and even if there was a threat, it's hard to care as the lead characters are rather dry and even as some of them are killed off throughout the series, it doesn't even warrant a flinch.
After having so much time sunk into this I feel obligated to share this review, and will leave it with this. Had the good elements from the series been extracted and put into a condensed form it may have been a more worthwhile watch. As it is, avoid LOGH unless you fall into the space junkie niche.
