French got their asses kicked because they were still thinking in WWI terms of positional warfare, not mobile, like the germans. The French wasn't able to deal with the mobility of germans very well, since they thought that sitting back and letting them come to them was the way to win the war...which was the way in WWI, but not II.

Germans also used their tanks in formations to break through, while the French, if they used tanks at all, used them one by one.

And the maginot line only faces one way, so once they get past it using the spearhead of the tank, their home free.
