It looks pretty overwhelming, but remember that all of our voting is by mail. I had my ballot and voter guides for at least two weeks before the election. I felt like it took some work, but I had plenty of time and info to make informed choices.
I am in a district that had 30 city council candidates. There are three seats in each district and I already knew a few of the folks running in my district, so it was pretty easy.
Overall I really liked the rank choice, especially for mayor. There was one candidate I really didn't like and I did not really have to choose between the other front runners based on who I thought had a better chance of winning (I also didn't have a clear favorite between them).
We do all of our voting by mail and get a pamphlet with most of the serious candidates. It is really great and we have like two weeks to work on it. It isn't like we showed up at the poll and were confronted with this and had to fill it out on the spot.
