I prefer orchestra seats to Mezz seats. For me Mezz seats, there always seems to be something block blocking out sections of the stage. And in front row Mezz there's often a bar, so you have to slouch to see under or lean forward to see over. If I go Mezz I ussually go about center fourth or fith row.
A little known fact is that in the original screenplay, Pan's Labyrinth was Pan's FLAByrinth. Hmmmmmmm...glad they changed it.
