It's awful because the stroke orders are mostly wrong, the word definitions are way too simplistic and there are no example sentences unless you go into the dictionary (if even there), and the games are mind numbingly boring and don't even reinforce knowledge (whack-a-mole? wtf?)

Well, lots, but not "mostly." Not to exaggerate, about 15% of the kana stroke orders are wrong (largely katakana). See this post for a listing.
Definitions are often indeed too simplistic. I haven't noticed example sentences even in the dictionary.
I'm going to speak up to defend the much-maligned whack-a-mole. It has one good point, which is to train quick recognition. Set on hard (where it has three distractors as well as the correct word), it's actually useful--for example, I just used it to train myself to distinguish りょうり from りょこう quickly. Now, having said that, I still think it's a stupid game about 95% of the time :-)

Many of the games are also horribly broken to the point where they don't work for certain lessons and you just need to go use a different game to get past it.

This, alas, is very true of the last two and most interesting games in the program--the ones having to do with writing kanji from readings or from english. How depressing to find that the games are available for a given lesson but don't give you the words from that lesson, but instead default to the words from two or three lessons back!

I'm deeply disappointed that it isn't a better program. That said, though, I am still going through it--it's just a lot less reliable than I'd hoped it would be.
