I find that it has too many magic commands built-in so no-one really gets to learn the under-side of what's actually occuring so when it eventually breaks like everything does, you have no idea what you did wrong. An example would be how the git pull command is basically a bunch of different git fetch and merge commands.

Yes, but if it didn't exist people would say git's bad because everyone copies the same alias from StackOverflow, and it should just be built-in.
