Hmm, cant please everyone i guess.
After watching 3 seasons of Black Mirror some of the endings were expected.
Crocodile... was very well executed, the plot and the ending.. the real ending with the hamster/ rat thing in a cage... thats a solid 10/10 in my book.
3/10 lol, wow
As if the guinea pig was even necessary. She was doomed the minute she hit the investigator. Her files and the reports she'd submitted up to that point would be a paper trail leading right to the murderer. On top of that the episode also just completely forgot about the hotel clerk another witness who could lead the cops right to the killer. Crocodile tries to be one of those "It was the perfect murder, except for one mistake!" type stories but actually it was dozens of mistakes. There was no way she would get away with it.
In fact the guinea pig was the last thing that should have done her in. Those things have terrible eyesight, it wouldn't have seen crap.
I saw the guinea pig's role coming from a mile away. They made such a big deal when the insurance ladies partner bought it - that I knew it had to play a part at some point.
And as @G-com says there were many mistakes that came from this episode. The paper trail - the guy who was hit would of followed up with the insurance company and another insurance person would have gone through the exact same process.
My biggest problem was that the only way the recall machine worked was by the insurance lady asking the witnesses questions and getting the person to really imagine what was going on in that exact moment. But when it came to the pet, they got it instantly? Didn't need to jog it's memory with the smell of beer or play it a song? I should have mentioned this in my review above. And I thought that the baby being blind was a bit, eh - it added a bit of sadness, but i wouldnt call it a plot twist. It added one extra line of dialog and that was it.
Sorry for the rambles, I am glad you liked it, I dont at all want to take that away from you. But just my personal opinion.
Was Crocodile your favourite episode??
