Nice to get a glimpse into what Mickey's doing on his own during Season 2, and effective as a prequel, explaining where he learnt about the school to investigate it, an event referenced in the episode itself.

Showing more of Mickey as a hacker is also nice, and there's a Torchwood reference which is always great.

Again though, they ruin the episode itself by showing the monster, and this time it's just standing there in a school corridor.

I want to give this higher but that literal last second of footage ruins it.
