I don't have as much time to watch dramas but I can make some time for movies at the moment. I'm looking for something similar to the ones I have previously watched. If you have similar recommendations please let me know, I'll leave a list down below.
Strobe Edge
Kinkyori Renai
Sukitte Ii nayo
L♥DK
Bokura ga ita Zenpen/Kouhen
Ao Haru Ride
Kanojo wa Uso Wo Aishisugiteru
I haven't seen any of the movies you listed except for L♥DK  ( and all those you listed look so good that i added them to my PTW list lol) ♥
and since you seem to be lookin for a manga/romance movie ♥ maybe you'd like these two.. their both pretty good ♥

Kimi ni Todoke

and

Lovely Complex

Thank you very much I will definitely check them out!
I second Kimi ni Todoke. :)

I think you should also try to watch these:
Paradise Kiss
My Rainy Days
Tada, Kimi wo Aishiteru
Train Man: Densha Otoko
Solanin
Runway Beat

Some other manga based ones are Kyou Koi wo Hajimemasu, High School Debut, Paradise Kiss, and Kimi ni Todoke like the others said. And for future reference: Heroine Shikkaku (No Longer Heroine) also recently got a movie but I can't find translations yet, Orange is one that is still theatres so it hasn't been translated yet. Wolf Girl and Black Prince is getting a movie sometime this year.
