I see three reviews here, all positive.
While most of us who were there back in the day don't need to be told the Emperor has no clothes--and even in the greatly improved second edition he's merely sporting a well-placed tea towel--I think that what follows needs to be said.
The Lunar Exalted of the First Edition were just not very good. Each type was meant to function in a different milieu: Solars as the standard fantasy hero, for instance, and Sidereals as a kind of divine Man In Black. The Lunars were placed as savage, Conan-style fantasy, which could have been interesting, save for a few factors:
1.) Their history just wasn't particularly compelling. The sum total of their achievements in the 1500 years between their Exile and the start of the game can be summed up in a short paragraph. And before the Usurpation of the Solar Exalted, they were even more vague.
2.) Whoever wrote the powers for them did not do it particularly well. Some charms are literally useless, while the sequence of attaining powers resembles less the trees of any other Exalt type, and more like clouds instead. Further, while other Exalted took vague direction from their World of Darkness counterparts, the Lunars sharply resembled the Werewolves: powerful, brutal, and despite whatever roles they might be meant to take, ultimately a warrior at heart. And while the Lunars had tools to make them perfectly effective warriors, these were more or less mandatory for any long term survival and also permanently impacted a character's ability to disguise himself--especially painful for a playable character type with amazing shapeshifting powers.
3.) The pitch of the Lunars within the book was also more than lacking. Above and beyond the relative lack of history or general relevance to the setting, it's very clear that whoever was writing large portions of the book took "Barbarian" and "old World of Darkness Garou" and ended up with savage heroes who didn't just eschew advanced civilization, they actively warred against it, complete with raping, burning, and pillaging. Lunar concepts were by and large shoehorned into various shades of Hates-Indoor-Plumbing.
The first edition iteration of the Chosen of the Moon was easily one of the least-liked options for playable characters, and the fanbase rejoiced when the Manual of Exalted Power: the Lunars came out several years later. It isn't perfect, but it's much better than this.
