I've actually heard very good things about the rear mezz of the Marquis also, though I've never sat there.
I have been in the fourth row center mezz (for Drowsy) and first row left mezz (for 9 to 5) and they both afford great views, though the proscenium blocked off a small bit of the action on one side during 9 to 5 because I wasn't center. But I think you'll be fine anywhere in the front mezz.
