Although not as good as Lateralus, this album is awesome.  The popular tracks are probably the best ones.  All powerful, with full viens, ready to explode!  There is some filler in this album which is why I didn't give it 5/5.  Definitely a good album to own.  A bit different in style than Undertow and Opiate, which were more stright up edgey rock'n'roll.  Aenima and Lateralus get less technical in the guitar work and get more artsy and moody.
