This weekend, "Dolphin Tale 2" hits theaters with the further fictionalized adventures of a real, live dolphin with a real, fake tail. In that spirit, we bring you 10 of the most unnecessary sequels ever.

This weekend, “Dolphin Tale 2” hits theaters with the further fictionalized adventures of a real, live dolphin with a real, fake tail. In that spirit, we bring you 10 of the most unnecessary sequels ever.

10. “Escape from L.A.”

Sure director John Carpenter and star Kurt Russell return, but everything about this sequel felt meh. Did we really need a Snake Plissken surfing scene?

9. “Alvin and the Chipmunks: The Squeakquel”

The first movie was an assault on the senses — we never would’ve thought you could make those furry bastards’ voices more annoying — but most egregiously it was a terrible kids movie that should’ve never had a follow-up, let alone the dumpster fire that is “Chipwrecked.”

8. “Weekend at Bernie’s II”

We love when ridiculously unlikely plots like, say, two friends have to pretend a corpse is still alive, get revived for a second go-round, but we also wonder, whatever happened to Jonathan Silverman?

7. “Son of the Mask”

Ten years after “The Mask” put Jim Carrey on the cinematic map, we got a thoroughly unwanted sequel with … Jamie Kennedy? Ouch.

6. “Caddyshack II”

No Bill Murray. No Rodney Dangerfield. No Harold Ramis. Why did this abomination need to be thrust upon humanity? Oh that’s right, so Chevy Chase could get paid.

5. “Look Who’s Talking Too”

The talking baby gag got old in the first movie. This one added Roseanne Barr and that awful “Too” title joke. Fortunately, director Amy Heckerling recovered to make “Clueless.”

4. “Speed 2: Cruise Control”

Another returning unlikely plot, this one turned the speeding bus into a speeding boat and replaced Keanu Reeves with Jason Patric, one of the few actors who can wear the badge of being “the poor man’s Keanu Reeves.”

3. “Staying Alive”

A sequel to “Saturday Night Fever” in 1983?! Wasn’t disco (well) dead by then? Not as dead as John Travolta’s career after this utter flop. At least we were treated to the most ridiculous and narcissistic ending in cinematic history — Tony Manero’s line, “You know what I wanna do? Strut.”

2. “The Godfather: Part III”

Nearly 20 years after “Part II,” this thoroughly unnecessary sequel is the major black sheep in the “Godfather” family. Francis Ford Coppola’s career skid continued after that.

1. “Blues Brothers 2000”

Resurrecting the iconic Blues Brothers sans John Belushi isn’t exactly in good taste, but doing it for this abomination — complete with a precocious Poochie-esque brat — should go down as Hollywood’s worst crime against humanity.
