This was certainly a great episode- back when future creatures were original and creative. The fact that the creature remains a mystery is awesome and the storyline with the creatures capturing rather then eating right then and there is much more interesting. Connor's acting is pretty good and its nice we see more of the mysterious "cleaner". The ending with Connor plunging after Abby into the future is a great way to end the episode especially with the battle with the MerQueen. Overall I give this episode an A+ - OliverLeekfan
