1. No it wasn't.
2. It wasn't historically accurate.
3. The cry of "freedom" at the end was ridiculous, because there wasn't freedom any fucking where in europe at that time and the Scots weren't promising to bring it, only another goddamn king. If anything, they'd be worse off, since at that point in time England was the most liberal country in europe (outside of the republics), with the magna carta and all. A return to feudal Scottish rule probably would've been a step backwards, which is saying a lot in its sadness, but still.
