The Doctor races against a deadly alien pathogen and some very nasty birds.

After the breakneck plot twists ofFugitive of the Judoon,this weeksDoctor Whois going back to basics.

But just because Praxeus isnt as flashy as its mid-season predecessor doesnt make it a dud.

The episode zips along at a nimble pace, ping-ponging from continent to continent for a whirlwind adventure.

(Its one of the most unpleasant deathsWhohas delivered in recent memory.)

In a nasty twist, the reason Praxeus is flourishing on Earth is because it thrives on plastic.

Even we humans are stuffed with tiny micro-plastics we ingest through our food and water.

But even with its overstuffed cast list and slightly silly plot, theres a lot to like about Praxeus.

The entire hour looks gorgeous (and expensive!
