Pretty awesome
I wasn't sure what to expect going in to watch the flash, and having now watched it, I'm not positive what I just saw. I do know that it was hilarious, and that the squid was just crazy. What made it stand out was the human's nonchalant reactions to what was going on. I mean, it's a giant freakin demolition squid.
Only thing that keeps it from a ten was that the narration was rather quiet compared to the rest of the movie, and it through it a bit out of whack.
