As a russian, I can add to this. Lettershapes in cyrillic cursive look nothing like printed ones. When I started school I could read perfectly, yet handwritten notices on the door looked like greek; I had to ask adults to read them.
Admittedly, there is a good reason for cyrillic cursive's existance: shapes of printed letters are just not suited for writing them by hand. Whereas in latin most letters can be printed with just one or two pen strokes (even disallowing retracing), cyrillic letters take two or three at minimum. Probably related to the fact that cyrillic mostly developed after printing was invented, and changed by acts of kings and church, while latin had a much longer and gentlier history.
