I have found Bodies to be a solid time travel crime thriller. I did think the final episode grinded its gears with the time travel concept.
Iris Maplewood goes back to 1890 and gets to talk to Hillinghead. She manages to make Hillinghead understand about Julian Harker/Elias Mannix.
What follows was a convoluted way to wrap the series up. Time should had changed once the conversation in the coach between Harker and Hillinghead differed from previously.
This is followed down the chain. The deteriorating relationship between Polly and Harker. In simple terms the timeline altered and this would had changed circumstances.
I have no idea why Polly stayed with Harker or even kill for him. In the new 1941 timeline, Charles Whiteman is shot by the police not hung. Although I wondered why did Whiteman talk to Hayden Harker on the phone when he did not need to. Also why did Esther have to die, unless this was something that would push Whiteman over the edge.
As for Shahara Hasan, she found that record a tad too easily. Just waltz in a pub, pick up a picture frame and its at the back. Been placed there 80 years earlier and not been moved or discarded!
It was all a bit too cumbersome although overall, this was an enjoyable series. Jacob Fortune-Lloyd stood out from the cast.
