Without your second post asking "how come", I was so sure that you meant "the modal rules".
The reason I made that comment was already explained. I thought your English level was better than to ask the elementary questions on modals. That's all, nothing derogatory.
And for the "do/ did you like the movie" question, this guideline may help you:
Regular / routine/ common / general question without a future or past time reference, use "do".
i.e.
Do you like English movies?
Does your boss yell at you frequently?
Do your classmates tease you ?
When you refer to / ask about something happened in the recent past, like the movie your brother just saw with his friends few hours ago, or the birthday party of your friend you didn't go last evening, use "did".
i.e.
Did John go to the movie with you guy?
Did everyone have a good time?
How many drinks did you have ?
Did you take a taxi home?
