I don’t have a favorite but a few I liked a lot.
The Adventures of Buckaroo Banzai Across the 8th Dimension: great fun crazy cast.
Cirque du Freak: The Vampire’s Assistant. Such a strange world. I would have loved to see sequels.
Pandorum: Clever scifi horror. Unique situation and setting.
Rustlers Rhapsody: The main character is a genre savvy singing cowboy from 1940s westerns transported to a 1980s western. The bad guys have to team up with some spaghetti western villains.
Yeah C# gets a bad rap. I spent a decade developing in C++, and Java before switching to C# because of program requirements. Now I never want to go back.
