Here is a concise summary of the text, which appears to be a humorous, sarcastic review of three shark-themed B-movies:
**Movie 1: Zombie Sharks**
* A scientific experiment goes wrong, turning sharks into zombie-like creatures.
* A group of people, including a soldier, try to survive and eventually blow up the sharks' base.
* One character is swallowed by a shark, only to be retrieved and then die again after turning into a zombie.
**Movie 2: Sharkenstein**
* Set in 1942 Germany and later in 2015, a Nazi scientist creates a killer shark, "Sharkenstein", using Frankenstein's brain and heart.
* Sharkenstein evolves into a land monster after being struck by lightning.
* The monster is eventually killed, but not before a second Sharkenstein is hinted at.
**Movie 3: Piranha Sharks**
* A scientist merges piranha and shark DNA, creating small, deadly creatures that evolve to breathe air and fly.
* The creatures wreak havoc, prompting a team of exterminators to save Manhattan from a radiological attack.
* One exterminator sacrifices himself in a bizarre, unexplained manner to save the world. The movie ends with a hint that the creators of the piranha sharks are still at large.
