It WILL be Top Gun:  Maverick 

Tombstone II was a disappointment, turns out it was just a documentary about the frozen pizza.

Aliens

Star Trek II-Wrath of Khan

The Empire Strikes Back

The Dark Knight

Terminator 2

Thor: Ragnarok

Mad Max: Fury Road

Is Fury Road really a sequel?  

I thought it was great.

National Lampoon's Christmas Vacation

OR...

Ninja Turtles II: Secret of the Ooze 

Home Alone 2 is a pretty banger sequel.

According to Rotten Tomatoes, the best sequel of all time is...

Paddington 2.

@Ulty Nice find!  Though I would argue they are conflating "best" with "most liked" though the distinction may depend on how people want to define the terms.

The Last Jedi being at #45 really makes me question the legitimacy of the list.   

I wasn't sure how to categorize the Marvel moves - I'm not sure they really all count as sequels to Iron Man.  But I would count Endgame (#22) in any case and that would be on my list as well.

My previous submissions came in at #27 and #25 so that's not bad.  

Porky's II

I see someone else had Cinemax and/or HBO when they were in middle school...reading the TV guide...seeing Porky's II was going to be at 12:15am on a Saturday.

Wild Orchid II

Evil Dead II

Dawn of the Dead
