It appears a lot of Reviewers don't "get" this game. It's *much* better then they lead you to believe.
The dungeon and combat mechanics are great as well as adequately challenging. Graphically from a technical standpoint the game looks like early PS2 - Late Dreamcast. However that doesn't matter because artistically the graphics are charming. Each new piece of equipment changes your characters appearance. The more you combine weapons and armor the more you can customize your character to how you see fit. The story is typical RPG fair but one never plays a Roguelike for it's story. Much like one never plays a Mario game for it's story.
In this case if you were looking for an RPG that had a strong multi-faceted plot then yes you would look elsewhere. There is no voice acting and there aren't really any FMV Cutscenes. However those looking for a new (if you haven't played a Roguelike or Mystery Dungeon before) experience, or if you're a veteran seeking a new challenge, you could do far worse then pick up Nightmare of Druaga. Especially when it's only $10 bucks now new in most stores. I strongly recommend giving it a chance. So long as you know that it does not play like your standard JRpg you should be pleasantly surprised.
