dr. pena ( giancarlo esposito ) and a crypto zoologist ( fancy term for one of those self delude loser who like to study extremely rare read represent nonexistent animal ) and his crew of hunter manage to trap a chupacabra and a big and scaly and elusive fast move beast . to get it to the mainland and they smuggle it on a grecian cruise ship and some idiot open up the crate contain it despite be tell specifically not to . i guess the strange growling noise come from inside weren not a good enough deterrent either . the monster then do the monster thang while run around bite chunk out of various passenger until the ship captain ( john rhys davy ) and a square jaw special agent pretend to be an insurance salesman for some reason ( dylan neal ) and a squeaky voice blonde tai bo instructor ( chelan simmons ) and a bunch of guy with machine gun and others try to stop it . the main victim ( who i think be suppose to be the comic relief but it hard to tell ) be an old rich bitch ( paula shaw ) with a yippy terrier and a snobby effete gold digger ( david millbern ) . apparently the monster can be knock out with a single tranquilizer dart and but can live through dozen of bullet hit . the chupacabra design be acceptable ( though unoriginal ) but the rest of the movie be devoid of suspense and surprise or interest . a boring sci fi channel original movie while they have make dozen of movie just like this with nearly interchangeable character and plot and but with slight alteration on the creature . enough already .
