Spoiler free review: I give it a 10. No particular reason that I wish to share.

A strong ending for one of my favourite series of Jago and Litefoot. The beginng was a little bit muddled I felt, but once the plot really gets going it becomes a worthy and dramatic finale, with many poignant moments for all the regulars. And of course there is an intruiging cliffhanger for series 6 - can't wait to hear what's next for the investigators of infernal incidents!

As hinted at by another reviewer, it's tough to talk about this one-- at all-- without including spoilers. I'll try to tread lightly, but consider this a warning. The fifth series was very much a return to form for the Victorian duo, and aside from the uncharacteristically off-putting Gluttonous Guru, a lot of spooky fun. Events at the end of the Bloodchild Codex, however, suggest a very different story than what we wind up getting here as our heroes finally confront Guinevere Godiva. (Last chance to stop reading!) Going into the second part of Final Act was so jarring that I felt like a marketing team had burst into the writers' room and demanded a rewrite of the final act. The climactic showdown largely jettisons the sinister conspiracies and enigmatic cast members of the 60s London stories in favor of re-enacting a classic Who moment shot for shot. I'd give the first 75% of this two-parter a 9 or 10. Watch that last 25%, though. It's a doozy, and your enjoyment is likely to hinge on whether you perceive it as "affectionate homage" or "lazy retread."
