Primeval is a British TV series. The premise is that temporal anomalies start opening up at random in England and various prehistoric beasties come through and start eating people. The Government sensibly decides that that this information is far to important to let be spread around to the common people who might [gasp] start buying guns to protect themselves and their families from being a lunch-o-saurus for some random monster. Instead they hire a group of rebellious scientists and zookeepers to handle matters and keep it all under wraps. Apparently, only the Government can be trusted with handling this crisis but only people who despise the Government can be trusted to handle it for the government ... or something.
Politics aside, it is a tremendous idea for a series. The actors are good, the special effects are tolerable, the stories are engaging, and I really enjoyed the first three seasons in spite of the head-pounding stupidity of all of the smart characters. After Firefly and Avatar --the Last Airbender, this is my next most recommended series.
Just ignore the fact that the leader, Nick Cutter displays his genius by making wild-ass guesses, committing all efforts and resources to the the guess, and then getting lucky. All of the other characters view this as a sign of his genius; I viewed it as a sign that the team desperately needed to reassign him to a less responsible position before his lucky streak ran out.
Also, don't spend a lot of time wondering why this brilliant team, weeks after their job starts still don't carry basic equipment for capturing dangerous animals, items like capture poles, ropes, chains, nets, net guns, cages, traps, snares, and bait. They carry no life-support equipment for hostile atmospheres, no mosquito netting, no cold-weather gear. They carry no night-vision equipment. The temporal anomalies have electric and magnetic effects and the only instrument they bring with them for the entire first seasons is a magnetic compass. If they had been prepared, nothing much interesting would have happened.
There are other things you shouldn't ask yourself. Let your problem-solving faculties relax, and you will enjoy the series a lot more.
