It boils down to this - if you want to sit down, put your feet up and be royally entertained by a fast-paced action drama for four seasons, you will love this. If however you get extremely annoyed while analysing an episode in micro-detail for the rest of the week this isn't for you.

The final series revolves around the acquisition of a half-billion dollar piece of technology. The pace rarely lets up and it is satisfying to see how Michael consistently outsmarts his enemies (well, most of the time). The constant twists and turns are overdone by the end, but you will always be eager to find out how the story concludes.

When evolutionary zoologist Nick Cutter discovers prehistoric creatures alive and well in the present day, the natural world is turned on its head and humanity faces a threat to its very existence. Unexplained anomalies are ripping holes in the fabric of time, allowing creatures from the very earliest stages of Earth's development to roam the modern world. Cutter and his team struggle to keep the looming disaster secret while dealing with savage dinosaurs and other deadly foes.
