It's a decent book. Lots of monsters, evocative art. The monsters are those you remember for the most part, and they have been slightly improved mechanically for the most part. The dragon creation process, especially, is better than in 3.5 IMO. Downsides are uneven amounts of fluff (some entries are pretty well done, though) and the lingering problem of spellcasting monsters having a list of abilities that you will need to cross-reference the PHB for. Didn't buy it as I'm 4E for a while, but if you're looking for an in-print 3rd Ed MM, this is the way to go.
