Some of the complaints I'm hearing aren't actual flaws, just opinions.
There's a difference between cartoony, and exaggerated. Borderlands is cartoony, this game is more exaggerated.
Not being able to jump is literally a non-issue.
Combat is pretty fun, in my opinion. Been to long since we've had a good Fable-esque combat system.
The facial animations seem kind of wooden, and the whole world is a bit cliche.
Am I the only one who thinks the actual story of you character is awesome? Better then Skyrim's for sure.
Also, Reckoning mode is bad ass.
Ugh, not being able to jump across a five foot gap... or worse down a five foot drop to that path that would otherwise take you an hour to get to is incredibly annoying. Very restricting, only multiplying the linear feel of a game, let alone the combat options that are non-existant from not having the ability.
That's a rather broad statement. I rather like the cartoony looks of many japanese games, like Dragon Quest VIII, Valkyria Chronicles and so on. But this just falls flat for me.
Realistic aesthetics are not a problem for me so much. I've enjoyed many game with sprites, or big eyes. I can even get over the lack of jumping in many games, providing the games are an enjoyable experience.
Realistic mechanics in an Action RPG?
Well, maybe that is asking a bit much, but something about this game just makes it feel dated to me.

The narrative involved is pretty slick though, there is that.
