You see all the downstage action, but this show has a lot of video projections. Being high up in the balcony means the top curtain (right below the proscenium arch) cuts off thu top of the video projection screen. You don't miss anything important, but you also don't get the full effect of the production. Sound is loud and clear (trust me haha). Legroom is tight (what else do you expect at a Broadway theatre)?
Front row of the dress circle, third seat in from the left of the house. Great seat. You miss the very edge of stage right, but most of the action is in the center, and you can see all of the images/text on the screen at the top of the stage.
Decent seats if you are tall enough. I am 5'10" and I had to look up to see the action going on. Granted, these are RUSH tickets so I did pay at a discount. You do see everything going on on stage though. Very good for the price.
