I liked Anaconda 2 :) one of the more macho manly man characters in movie history, aside from that dude in Frankenfish, hilarious.
As for Anaconda vs komodo, I´m not sure. I know that in Anaconda Vs Python OMG SPOILERS!
SPOILERS I SAID! BEGONE NOW OR SUFFER AND BITCH FOREVER ABOUT THEM!
In Anaconda Vs Python they mate, or something.
Oh, and on the subject of using firearms agains swarming foes, I believe they are a long, loved tradition of B movies. From locust to bats to more locust to spiders to wasps, fairies, people just don´t seem to learn.
Back when I was a kid in the late '70s, everyone was afraid of “killer bees.” I remember seeing a made for TV movie based on them attacking or something. Mostly what I remember was that at the end they somehow tricked the bees to attack a car, and drove the car into the Astrodome. Then they turned down the AC.
