King Kong did it better
In the same vein as the Colossal Man/best (57 and 59) this movie suffers from how bluescreen was used, and some of the shots just look very off. In some of the block-shots they have just used closeups to normal animals, and it does not make them look like giants, really. The Cyclops is reminiscent of the War of the Colossal Beast (58) prosthetic, but a bit bigger.

King Kong (1933) had more ingenuity in its monstershots and cost a great deal more, and it shows.
