Little Fockers (2010)
The Comedy: No-nonsense Jack Byrnes (Robert De Niro) decides it's high time he sorted out a successor for when he eventually croaks it, which of course means bumbling son-in-law Greg (Ben Stiller) wants a shot at the title. Hilarity ensues.
Except, no, it doesn't.
Lowest Moment: Greg has to inject Jack's penis.
We can't remember why, but yes, this actually happens. We're surprised De Niro didn't tell the writers of this sequel to Fock off.
Ace Ventura: Pet Detective Jr. (2009)
The Comedy: Josh Flitter is Ace Ventura's son, imaginatively called Junior, and he's inherited his pa's gift for gabbing with gorillas and other furry things.
When his mum is accused of stealing a baby panda, Junior steps in to save the day.
Lowest Moment: Two words... Farting. Animals. *forehead slap*
Blues Brothers 2000 (1998)
The Comedy: The whole point of the original Blues Brothers was the appeal of Dan Aykroyd and John Belushi right? Which makes this sequel even more befuddling – Belushi had been dead 15 years when Aykroyd and co decided to do a follow-up.
Which means poor old John Goodman gets the thankless task of stepping into Belushi's shoes as a singing bartender. Tenuous.
Lowest Moment: By the end of the film, we're lumbered with four Blues Brothers, and we hate them all. Probably not what director John Landis was going for.
Arthur 2: On The Rocks (1988)
The Comedy: So, $750m is a lot of money to lose, but Arthur (Dudley Moore) manages it in this sequel to the 1981 hit.
That's the least of his problems, though, as wife Linda (Liza Minnelli) wants to get preggers...
Lowest Moment: John Gielgud gets little more than a cameo. Sure, his character's dead, but still...
Smokey And The Bandit Part 3 (1983)
The Comedy: Blissfully only 85 minutes long – but then, the plot can barely even fill that time, as Big and Little Enos bet Sheriff Buford T. Justice that he can't drive from Florida to Texas in the time he claims he can.
Naturally, the Sheriff takes up the bet – and he'll lose his badge if he fails.
Lowest Moment: All of the chases, which struggle to get anywhere near to the original film's thrilling set-pieces.
Fletch Lives (1989)
The Comedy: The eighties were the worst for unnecessary comedy sequels that ruined their predecessors, and Fletch Lives is perhaps the best example of that.
Though the character of Fletch (Chevy Chase) was, admittedly, rich with possibilities, this sequel kills every one of them dead as Fletch heads to Louisiana to investigate a house left to him in a relative's will. Number of laughs: zero.
Lowest Moment: Any time a hideous Southern cliché is trundled out in the desperate search for laughs. So there's the spiritual leader, the fat thug...
Caddyshack II (1988)
The Comedy: This time it's Dan Aykroyd hunting gofers, after Bill Murray stayed well clear of this ill-advised sequel.
Sadly, Aykroyd's involvement is the funniest thing in a sequel that inserts a hideously obnoxious Chevy Chase into proceedings, with the plot following what happens when Jackie Mason buys a golf club – and turns it into the devil's playground.
Lowest Moment: The gofer starts talking. We wish we were kidding.
Police Academy 5: Assignment: Miami Beach (1988)
The Comedy: Where there are that many colons in a film's title, you know you're in trouble. It's certainly true of this fifth Police Academy movie, which contains the usual mix-ups and bust-ups as Lanssard heads to Florida to receive an award (presumably not for stupidity).
Lowest Moment: Just how many camp chase scenes can one film contain? According to Police Academy 5 , at least a thousand. Maybe a thousand and one.
Superbabies: Baby Geniuses 2 (2004)
The Comedy: We can only assume that Jon Voight was thinking about a tax bill when he signed up to this bag of tripe.
He plays a media mogul who's kidnapping kids because, er, he wants to brainwash the world or something...
Lowest Moment: Voight starts talking with a German accent...
Dumb & Dumberer (2003)
The Comedy: Actually a prequel, but still a sequel to the Jim Carrey/Jeff Daniels flick about two incomprehensibly dumb guys whose stupidity gets them into all sorts of icky scrapes. Here we discover how they met.
Yes, they're still imbeciles. Just YOUNGER imbeciles.
Lowest Moment: Genuinely funny actor Luis Guzman gets dragged into this car wreck of a movie...
