I have always liked The Who since the sixties, and have been gradually building up a complete collection of their studio albums. This album almost completes the collection ('My Generation' is not on my wish list and the only remaining item is 'Odds and sods' which mostly duplicates tracks I already have).
Since I starting collecting and listening to Who albums I was not previously familiar with, my appreciation of The Who has increased.
The question about his album is whether it can really be"The Who" without Moon. The distinctive fills are certainly missing, but otherwise the sound and songs fit into The Who mould. Therefore, while this album is not one of their best, it is a worthwhile addition to The Who catalogue. It should not be dismissed and it should not be ignored. If it had been released by a group without The Who's background, it would probably have been declared a triumph. That said I would rate Tommy (preferably SACD if you play it back in surround) and Who's Next as better. For a live album - the Deluxe edition of Live at Leeds (which largely duplicates Tommy - showing they could do it live).
