Ass Pull: The whole "Michael replaced an ambulance worker for himself at the end of H20" revelation at the start. It wasn't exactly a trueAss Pull, since producer Moustapha Akkad had planned the idea to get out of H20's ending ever since they shot it, but even hardcore fans didn't buy it.
It was originally worse; the Michael Myers in H20 wasn't actually Michael, it was an obsessive fan. It may have made more sense, but it would've been a very hard twist to defend.
Par for the course for Akkad, who signed off on the ending of 4 with Jamie taking over as the killer in the series, but had no intention of following up on it.
Alternative Character Interpretation: Michael Myers wasn't in the whole movie. He was there during the opening scene where he killed Laurie but the rest of the movie involved the serial killer fanatic that Myers encountered in the opening movie took his place, while the real Myers is just hiding somewhere. After he killed Laurie him passing the knife to that fanatic could be seen as his way of saying "I'm retired".
Jim tends to be fairly well liked, primarily due to his funny one-liners and style
Brad Loree as Michael Myers is also praised by many fans, claiming how he harkened back to Nick Castle from the original film with his performance.
While her performance isn't the best, Tyra Banks' character Nora has grown in popularity over the years, mostly because she seems to be having fun and doesn't seem either lifeless like Sara or Donna or Too Dumb to Live like Jen. This has caused many to wish she had been the Final Girl.
Resurrection is like a weird Alternate Continuity hack job full of cheese that kills the main heroine early on and has Michael Myers beaten by some has-been rapper with Kung-Fu. It's like they're saying 'The woman who knows the killer for years, is his sister and probably the one you'd assume who be able to beat the bad guy once and for all is a boob we can just kill and discard in favor of this goofy rapper guy. It's less a Halloween film and more a "Wish-Fullfilment Fantasy/Vanity Project" for Busta Rhymes.
By all accounts, Rhymes was the only person actually invested in the project. Everyone else simply collected their paychecks and hoped no one would read their resumes too closely.
The blatant Character Shilling at the beginning where Sara simply whispers the answer to a question in class, and her professor inexplicably hears her and goes on praising her with zero authenticity.
Something falls and breaks behind Sara, and her startled scream is so loud that she shatters glass.
Nearly all of Michael's kills are slightly hilarious. Impaling a guy with the camera tripod, or decapitating a girl with one stroke of a butcher's knife, for instance. Earlier than that, he bursts through a mirror (and presumably the wall it hung from) to stab a guy to death, whose dying screams of terror no one hears in the small house.
How does Freddie end up defeating Michael, one of the most famous movie villains ever? By jamming a sparky electrical cord into his crotch, comically electrocuting him.
When Michael pulls his Not Quite Dead routine at the end, there's an abrupt wolf howl for no reason.
Narm Charm: Busta Rhymes' entire performance as Freddie. It's completely out of place in a Halloween movie, yet he's the only one bringing any heart to the film besides the actor playing Michael Myers.
Sequelitis: This is an almost unanimously reviled film, often ranked as the worst in the series. It's also seen as completely unnecessary, given that the ending to H20 neatly wrapped things up and the writers had to go to extreme measures to retcon Michael's death.
They Wasted a Perfectly Good Plot: The cancelled continuation of this film would've been Laurie's son seeking revenge against Michael for killing his mother. One has to wonder why that idea wasn't this movie in the first place.
Took the Bad Film Seriously: As stated above, Brad Loree's performance as Michael Myers is considered by a large amount of fans to be the sole good thing in what is universally agreed on to be the worst entry in the franchise. To this day, some fans still hope that he gets a second chance to play the character in a much better Halloween film.
