Whenever I ask a girl out on a movie date, I usually pick something fairly funny, or scary. In my opinion picking a romantic film is a mistake, because most of guys dont really watch romantic films, so why should it be any different on a date. Secondly if the film actually has a good story in it, that can give you something to talk about. Moreover if it's scary, you can be protective if your date gets scared and for example kino her (holding her hand is good, it always worked for me).
Make her talk about herself, don't just DHV. The girl will be comfortable if she talks about herself, and it will also make you look interested not only in her looks, but also her personality and hobbies (girl likes when guy listens to her, because many guys don't, so it's one of the important values to have).
Do neg her, its always good to lower girls value a little
If she gives you IOI's and you want to kiss her at the end.(this is what I would do) Ask her if she want to kiss you, because that gives you three options to say:
-if she says yes then, well you know what to do

-if she says maybe, you say something like should we check.
-and worse case scenario, if something goes wrong and she says no, simply reply by saying "i never said you could".
If she gives you IOI's, and you can tell she's interested in you. Then just ask her out again or something. That would be the best move to make in my opinion.
I hope these help, most of them come from my experience and some of those tips I found out by learning about the game. Good luck
