The Tank That Love Built...
The Quiet Sound of Thunder
Jim and Spock aren't exactly lawless convicts, but neither are they model citizens of Earth: branded renegades, they search out the government's uncontrollable genetically engineered quasi-human superspecies in order to protect people. But when they stumble on a new clan of vampires, things take a turn for the unexpected, and it'll change both their lives forever.
Holy moly. This is great. It's like your average action flick, if your average action flick had an actual plot, backstory, compelling characters, chemistry between said characters, and depth.
Plus: Kirk walks in on Bones jerking off in a bunk bed. Two thumbs up!
