How does it rate?
Master's Degree - Pieces is not required reading, which means you can still function as a slasher fan without seeing it. I would recommend it, because it is a fascinating film within cult history. As for reasoning stated above such as the amount of gore, its exploitative nature, and the comedic elements it rates much higher. I would obviously sift through the piles of slashers and a bit from the giallo column prior to getting to Pieces. With a background in 80's splatter, you can advance to this film. Make sure you've earned your Bachelor Degree first.

The who's who list:
Producers:
Stephen Minasian produced Sean Cunningham's faux porn doc Together (1971). With Dick Randall they produced Slaughter High, Don't Scream: It's Only A Movie, and Don't Open Till Christmas.
Writers:
Secretly written by Joe D'Amato.
Actors:
Lt. Bracken Christopher George's horror career began with Lucio Fulci's City Of The Living Dead in 1980. He went on to do The Exterminator, Graduation Day, and Mortuary.
Mary Riggs Lynda Day George was married to Christopher and worked with him again in Mortuary. She was also in the not-so-terrible TV movie Ants.
Sgt. Holden Frank Brana was Simon's right hand man, he appeared in nearly all of the director's films.
The Dean Edmund Purdom was in Joe D'Amato's Absurd and worked with Simon again on The Rift. The producers of Pieces – Stephen Minasian and Dick Randall – provided Purdom with his sole director's credit with Don't Open Till Christmas.
Kendall Ian Sera worked with Simon on Mystery On Monster Island, Sea Devils, and The Pod People.
Willard Paul L. Smith is a great character actor with an eclectic resume: Midnight Express, Popeye (he was Bluto), Dune, Crimewave, Red Sonja, and Haunted Honeymoon among other lesser known titles.
Professor Brown Jack Taylor was most recently in Grand Piano. He also had a role in The Ninth Gate and Conan The Barbarian. Taylor worked with Simon on Where Time Began.
Music:
Stelvio Cipriani has an extremely long list of compositions but his re-released tracks on the Amer and Death Proof soundtracks are superb. As a note, he also scored Mario Bava's Bay Of Blood.
Director:
Juan Piquer Simon began his filmmaking career in 1964 making short documentaries. In 1977 he was given the opportunity to direct his first feature film. Where Time Began was Spain's answer to Jules Verne's Journey To The Center Of The Earth. Simon worked with Jack Taylor and Frank Brana who would one day have roles in Pieces. While making Where Time Began, Simon created a fantastic and surreal world with the use of actors in costumes, matte photography, and painted backgrounds. Though the world of special effects adapted to updated technologies, simon preferred a more classical style. He went on to direct Don't Panic AKA Satan's Blood, Supersonic Man, Mystery On Monster Island, and Sea Devils. In 1982 he made Pieces which eventually provided him cult fame. After Pieces he made The Pod People which was lovingly riffed in Mystery Science Theater 3000. Dirty War, Slugs: The Movie, The Rift, Cthulhu Mansion, Devil's Island, and Manoa: The City Of Gold followed. Simon may not be a household name, but for fans of the slasher genre, Pieces is a title that stands out.
