I got Mezz row F, on the right-center aisle last night. My friend was in a very similar location at a late preview.
The view is good, if a little farther back than an average mezzanine. But the seats were massively tight, worse than any mezzanine I've sat in.
That said, rush seats are reportedly extreme side orchestra with an obstructed view, so this is a better option than that. Though if you are willing to spend $70-80, there are probably better seats available through discount codes. And if not, this still did feel worth $45.
