I've read through the bad reviews of this room and can only say I guess different things appeal to different people.
We booked this one not expecting a huge amount, we're big Doctor Who fans, but found 'Worlds Collide' in Leeds to be one of the least enjoyable rooms we've ever done. (They were charging significantly more than an average room when it first opened, and it was just a pretty standard set-up with a couple of Doctor Who props thrown in. We expected more)
This one was very small, but the decor and soundtrack really helped to set the scene and keep the story going. They've made it quite high-intensity by having occasional moments where you have to stop what you're doing due to a 'threat', so it keeps the adrenaline up.
Others have said some puzzles didn't make sense, we didn't find this to be the case. We only needed one or two hints throughout, and managed to work out the answers to the majority of puzzles from the information given. Some are logic based, some are more physical. If you can't work something out, just re-read the information, it's all there.
The major let-down is the upkeep, it does need a bit of an overhaul. When we went a piece of one puzzle was missing (presumed stolen), and others looked like they needed some general repairs. New gloves would be good, and securing some of the floor pieces, as I tripped over some floor tiles. (It appeared that the floor tiles might be part of a puzzle, but they weren't so could just be glued down properly)
I think because we weren't expecting much we enjoyed it more, but it's a nice little game for a couple. I agree it wouldn't be suitable for bigger groups, but 2-3 is perfect.
