Considering it was just meant to be a proof of concept and only fly once or twice I would say that 71 flights, a max altitude of 78 ft(24 m), and 10.6 miles or 17 kilometers of travel, not to mention all of the footage from its on board cameras, makes Ingenuity an astounding success.

Especially considering the use of off-the-shelf Snapdragon 801.

There's some nice discussion about Ingenuity here: https://news.ycombinator.com/item?id=26177619

...This processor will have not flips on Mars, possibly up to every few minutes. Their solution is to hold two copies of memory and double check operations as much as possible, and if any difference is detected they simply reboot. Ingenuity will start to fall out of the sky, but it can go through a full reboot and come back online in a few hundred milliseconds to continue flying.

NASA's rovers have been kicking ass for the last few decades. Truly a testament to how great their engineering teams are

Definitely exceeded my expectations.

I think it exceeded everyone's expectations. I know I'm pretty astounded. I didn't realize it had been three years!

Based on how the rovers have over-performed on not that surprised (once we knew it could fly), but still very excited and impressed.

I was amazed it could fly at all in the thin atmosphere of Mars.
