PLEASE DO NOT READ IF YOU DON'T WANT SPOILERS.
OK - some parts I liked and some I didn't. Well acted, John was lovely as ever, it was great to see Amanda again and some pretty awesome traps.
BUT ARGH! JILL WAS INVOLVED??? SHE KNEW ABOUT IT ALL AND WAS STILL IN CONTACT WITH JOHN??? AND WAS PART OF IT ALL, AND ADMINISTERED HOFFMAN'S TEST??? WTF, SAW WRITERS???
Although I don't think they were still in love with each other by that stage. At least I hope not.
I think as a writer I will stick to my little John/Amanda/Zep AU! Dunno where canon thinks it's heading!
