These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Paul Sarone is a former priest from Paraguay who decided to become a snake poacher in the Amazon, catching them for rich clients. He arranged with his old hunting partner Matteo to lure a documentary film crew to a giant, man-eating Anaconda's home territory to use them as bait for the hunt. He incapacitates the team leader with a poisonous wasp before saving his life to win the crew's trust and offers them a "shortcut" that leads right into the snake's territory. The passengers are picked off one by one by the Anaconda, which crushes its prey in its coils before slowly digesting them alive. Sarone manipulates one of them into becoming his "partner", but he sacrifices the guy without a second thought when he prevents the others from shooting the snake when it grabs his ally, because he can't make a profit off a dead animal. He strangles a woman to death with his thighs when she's come to get revenge for her dead boyfriend. He is ultimately overthrown but escapes, and captures two of the remaining people inside the Anaconda's feeding grounds. He douses them with monkey blood and tries to feed them to the snake so he can trap it, while mocking their impending deaths.
Magnificent Bastard: Paul Sarone plays everyone like a fiddle in his quest for the snake. Only the expedition leader momentarily catches on to his play, but is none the wiser as Sarone paralyzes him with a poisonous wasp. He set up the whole thing with Matteo from the start, while keeping the clueless passengers in the dark that they were to be used as bait. He suggests to Owen Wilson's character that he needs a partner and they could split the profits, them lets the Anaconda eat him as soon as his prize is at stake. He's proven correct pretty much every time the crew decide not to take his advice. He seems to accept his impending death by a vengeful killer, only to swiftly murder her when she hesitates. His manipulation is so effective that he never needs to resort to outright violence until they finally catch on to him.
Narm Charm: Jon Voight's performance as Paul Sarone is absurdly over the top and its clear that whoever thought that casting Voight as a character with a thick ambiguously South American accent was a good idea was probably high. That said, in a film where the rest of the cast is so clearly apathetic about their performances its not hard to find yourself mesmerized by the pure and total hamminess of Voight's performance simply because unlike the rest of the cast he's actually trying. Winking at the heroes as if to say, "I told you so", when regurgitated by the snake is probably the high point of the film.
Anaconda: Between the weightless CGI models and the dull, dead-looking animatronics (though one could say that the CGI snakes are at least better than the animatronics), the anacondas are not inspiring fear. Especially silly is the short tussle between an anaconda and a jaguar, which looks like a wrestling match broke out at a taxidermist's office.
Hunt for the Blood Orchid may have had terrible CGI, but it doesn't compare to the sequels that followed it up.
So Bad, It's Good: Many viewers consider this film laughably stupid. Roger Ebert was one of the film's biggest supporters in this regard, often referring to it as "great trash".
