It’s another above average 4th doctor story no one moved

It's a cute Doctor Who does Jurassic Park. Outside of the novelty of hearing the Fourth Doctor, and the vashta nerada. There's very little substance. Taking a "Capitalism is bad route." With paper thin side characters. It's too short of a premise to have any real depth to it. Whether it be through character dynamics or how the villain is defeated. Not a need to listen to set. But not a bad one either. It's fine.
