Anime Academy reviews are the greatest of all time, bar none. There have been other anime review sites before, but few exist with precision of votes, calibre, and a masterful command of the English language as Anime Academy does.
Firstly, let me examine its setting: the setting of university. Anime Academy attempts to reinforce its credibility by usage of academic positions such as 'professor' in the hope that more users will agree with their statements. That's not to say it's bad, because, hey, I don't want to know that you're 35 years old with a second class honours in Creative Writing from a local university - that would merely ruin the general feel of the site.
Now on to the substance of the site: the reviews. Almost all - if not all - reviews either begin, or end (or both) with a paragraph of rhetoric in which the author makes a generalised comparison to other, more popular shows; while doing this, they distinctly point out the fallacy that popularity does not equal quality. Seldom do the reviewers focus on the less important bits: provable propositions of themes in anime, possible interpretations supplied with evidence, demonstrable symbolism, and overall consistency.
In conclusion, AA is not for everybody. If you're used to the generic user-generated reviews from popular sites such as ANN and AniDB, and you enjoy them, then I'd advise you to stay away.
