Took a break from Trek to watch Dark Matter and realized...I was still watching Trek.

Honorable Mentions:

• Inertial dampeners fail in both
• DM calls it "FTL drive" but it's warp drive in all but name
• Subspace communications
• Both have mirror universes
• Discovery's experimental spore drive is Dark Matter's experimental "Blink" drive in all but name

Edit: Had one I meant to include but forgot: Killer Barrels

Bonus: Has Detmer and Sam Kirk too.
