Same can be said for the entire dimension. The biomes are nice, and have a mystical atmosphere to them. I myself prefer the Twilight Forest, a mod that may not excel in matters of quantity, but the effort put in the dungeons and bosses can clearly be seen. Most dungeon consists of lame bedrock cubes, and while the modeling and texturing of both mobs and items has been done right, the API's of the mobs themselves are kinda lame.
While this mod is indeed huge, I'd say the quantity is predominant rather then the quality. This mod has been receiving lots of praise for its wide variety of mobs, items, dungeons, dimensions.
As a side note, mythical creattures mod SUCKs
For those of you(YES YOU!) that thing that ore spawn isn't hard, it is a very well made mod and years of effort put into it, normal Minecraft is easy to beat in like thirty minutes or so, this mod, no matter what you did, your NOT beating the king and queen in like 30 minutes, or even an hour, additionally, this mod would take literally forever to do everything in, and there is always more to explore.
