El Mundo Gira
I thought it was a stronger episode than I read in other posts. I'm mostly impressed with the public knowledge of the chupacabra in 1997 considering the folklore was established circa 1995 in Puerto Rico. It's a relatively new cryptid.
I do wish they had explored the potential cause of the yellow rain and lightning under a cloudless sky. If anyone ever read the YA horror novel Monster by Christopher Pike, it has a similar concept of humans slowly being turned into monsters from micro organisms infected waters. It's a story I've always wanted to adapt to the big or small screen.
The Spanish novella dialogue regarding two brothers pining after the same women and subsequent vengeance plot was enjoyable.
Tuco is ageless.
