I Prefer Leviathan (1989)
I know that on the Scream Factory Blu-ray Features of Leviathan(1989)...Alec Gillis was crapping on the film itself & on the FX he helped make on the flick.
With all due respect to Mr. Gillis...I'll take Leviathan a hundred times over your directorial debut, Sir.
I mention Leviathan because it too has elements of The Thing. But I also think Leviathan looks better, has a better soundtrack (Jerry Goldsmith), a better cast of characters, memorable scenes (like Peter Weller punching out Meg Foster and saying "Better. A Lot Better."), great lines of dialogue ("I Know You've Gone Through Hell." "Gone? Bitch, we're still here!"), and yes, in my opinion, better FX. Plus, at least it changed it up Somewhat but having the film take place underwater.
It's cool if people disagree. Just my opinion.
