Garland,
You probably missed my earlier post about seeing Star Wars at the Drive-Ins with lots of fond memories. I still enjoy watching the original trinity to this day.
To the rest,
Perhaps I'll give Casablanca another try, I recall not getting very far into it the first time.
And it may just be a stylistic thing with most movies from that time period The over-the-top dramatic acting, the miscast characters where white people were used for almost every ethnicity type, the portrayal of women as weak, feeble creatures whose who entire lives revolved around their protective man, the pacing of the scenes, etc.
