Yeah I'd say that's pretty accurate, it was an ok game. Some people hated it and I can see why, in many ways it felt like leveling on a mmo, solo. You grab a bunch of quests and run around to the markers, kill random shit, loot some random shit, and then go back to town to turn in and get some sweet xp. Once in a while there was dialogues, with choices, which a lot of the time were just do you want gold+xp or do you want no gold but more xp type of rewards and this kind of stuff.
It had a lot of stuff to do, but a lot of busywork mmo questing content, so people who hate that in mmos probably hated the game, but I like it for the most part, so I kinda enjoyed it, although some was really fucking annoying(like that desert zone at the end was retarded).
The difficulty was also mostly shit and uneven, with Nightmare being "lulz you might get one shot every now and then but other than that game is a snooze if you build a balanced party", and some classes literally broke the game in half in such a way that you could solo pretty much everything(the 1dmg tank thing, the flask based rogue, the assassin rogue, the melee mage thing and probably a few more). I don't remember the details but I think I one shot an endgame dragon with my rogue by stacking a bunch of shit to hit at once.
Story was so so, characters were meh, it wasn't great but it was an ok filler game.
