Have you seen “Primer?” It’s a hard-science genre sci fi movie – almost no special effects in the traditional sci fi movie sense but very dense on story and has an interesting geekster style. Kinda uncompromising – you either keep up or get left behind.

“Frequency” definitely required you to suspend belief in a big way, but it was one of those rare “feel good” geek movies. And the techie stuff is very subtly worked into the story.

And I still think they did a reasonably convincing job on the techie stuff in Gattaca. Sure, it’s highly-stylized, but they didn’t allow the tech to overwhelm the important stuff.
