If I had to do an analyse of this place I'd say it was a mixture of Hammer Horror, Horrible Histories and Carry on Films.

It's a very large chamber of horror style  attraction themed on some of the more gruesome aspects of London's past, such as the great plague and Jack the Ripper. However if you're after historical accuracy, or something of educational value this isn't for you. This places purpose is to entertain all the visitors that dare to enter through the doors. Something it does an admirable job  of doing.

You also stop at various points of the tour as the actors put on different shows and demonstrations.

There are a few tense scary moments  as well as a few shock, make you jump scares. A lot of it though is based on a dark camp humour. I think this works pretty well. An attraction like this can end up funny for the wrong reasons if it takes itself to seriously. Instead it opts for adding black humour to the proceedings, creating a good blend of terror and humour creating a fun and entertaining experience.

It's not somewhere for everyone. Families with young or sensitive children should best avoid this, and there will be people who won't be interested in the horror aspect of this attraction.

However if this doesn't put you off it's an attraction I would pay a visit to. At £15.00 entry it's not that bad value compared to some of London's other attractions. It's a fun way to spend some time when in London.
