Primeval is a British science fiction television programme produced for ITV by Impossible Pictures. Created by Adrian Hodges and Tim Haines, who previously created the Walking with... documentary series, Primeval follows a team of five scientists tasked with investigating the appearance of temporal anomalies across Great Britain through which prehistoric and futuristic creatures enter the present.

The first series followed the efforts of Professor Nick Cutter and his associates as they investigate the appearance of space-time continuum anomalies (called "earthquakes in time") that allow the passage of life-forms through that invariably threaten the lives of citizens.
La inceput am fost sceptic cu privire la aceasta serie deoarece multe seriale pe acelasi calapod sunt destul de bizare si nu atrag, dar am fost placut impresionat pana la urma. Actiunea, aventura si suspansul sunt bine proportionate iar actorii reusesc sa intre cu succes in pielea personajelor.
