Do people dislike this game because it's so different from ADOM, or is it just a bad game?

I am considering buying this from Green Man Gaming as it's £9 for gold tier members there, but it has very bad reviews. I love deep complex rogue-likes like the original Adom and Qud, but also love "coffee break" rogue-likes like Desktop Dungeons et al.... Is the game so maligned because it's much more like the latter, or is it just not a very good game?

"wild differences in class/talent balance"

"some other skill trees are so much more powerful that you're just crippling your character trying to focus on stealth"

"gear gets irrelevant very often. Loot shower"

As a very old-time ADOM player, these all sound like characteristics of the original ADOM. If you like games to be balanced, with all classes equally viable and without an overload of loot, surely you can't like the original ADOM? :)

Not saying UADOM doesn't need more work, but I played a game yesterday and it does have the feel of a shorter/more causal version of ADOM to me (which is a great thing to say). Just my opinion, though.
