THEY DON'T RUIN IT BY SHOWING THE MONSTER!

The acting and effects are pretty laughable, but I think the setup for the clockwork robots is extremely effective here. Giving us a perspective shot with the ticking but no more than that.

Showing the clock on the mantelpiece break is also great, and the shots pulling back as we can just hear the ticking. It all comes together to work really nicely.

Okay, this is one, interesting. I think at the beginning it had some "so bad it's good quality" with the fairly wooden acting and some VERY dated Effects, but the second Half is actually a pretty good Teaser for the Monsters of the fourth Episode!

I also enjoy the few Moments we have with the Clock, doesn't add that much, but hey it's a cool enough image!
