'Sharknado' -- Derek Hough REFUSED to Watch ... Because He Hates Awesome Things

It might have been the greatest television event of the year ... SHARKS climbing ropes, swimming down the 405, attacking helicopters and chasing Tara Reid up a flight of stairs ... but Derek Hough says he REFUSED to watch "Sharknado" last night.

Clearly, Hough was too closed-minded to see all of the awesomeness the made-for-SyFy movie had in store ... seriously, we counted 5 shark vs. man fatalities in the first 4 minutes.

In case you missed it ... the movie TOOK OVER Twitter last night ... with people begging for a sequel before the movie even ended.

Perhaps, "Lost" co-creator Damon Lindelof said it best ... writing, "I know it's only been 12 hours, but I'm not sure I'll ever be able to talk about anything non-Sharknado-related again."

People have already begun coming up with titles for the next installment ... here's a few we've thought up:

-- Psy-Clone: It's Raining South Korean Pop Stars
-- LouNami: Lou Rawls comes back to life to wreak havoc on the South Pacific
-- Heavy Rainn: Acid rain from a cloud that looks like Rainn Wilson melts San Diego
