At best a happy medium.  The director's "strategy" to use a no name cast, delaying the action to develop plot and attatchment backfired to say the least.  And if your looking for any realism in a mitosis or genetic sort of way forget it.  However, the creatures really have some pretty awesome action sequences.  And if any of the other ones have a little place in your heart this does at least kindle the fire.  But, alas, don't pay full price unless your in the dating scene or can have a kick ass time at the drive-in where The Bourne Supremacy played the earlier feature.:Spin:
