I am amazed by all the positive comments. In my opinion, the set is well below-average in terms of sculpts and paintjobs (nowhere near Blood War, Angelfire, or Giants of Legend), and slightly above-average in terms of creatures chosen. However, roughly half of the set consists of resculpts of minis that have already been released in one of the earlier sets.
Look at the minis: not a single one has properly painted eyes (whereas even some uncommons from previous sets have them); most rares have only one or two colors; there are two minis (Nightmare and Yuan-Ti Champion) that have armor which is apparently glued onto them (i.e. it looks ridiculous). I could go on all day long...
