- The original series is seen as having lost its edge by stripping away the killer Michael Myers' mystique, with later films attaching him to an ancient Celtic curse in order to explain his Implacable Man nature and why he kept targeting the Strode family. It eventually got bad enough that the producers had to declare everything after the second film to be non-canon when they made Halloween H20: Twenty Years Later.
If they really wanted to eliminate this series-derailing problem, then they should've retconned out the second film as well, because that was where it started.note In the original, Michael had no explanation beyond him being an escaped mental patient returning to his hometown to kill again, with Laurie Strode and her friends having no connection to him beyond circumstance. It's also left up in the air whether Michael is supernaturally evil or just extremely tough; while Dr. Loomis's final linenote leans towards the former, that's presented as merely the opinion of one man. The second film, on the other hand, not only revealed that Michael and Laurie were brother and sister, it also implied that Michael's seeming indestructibility was related to the occult. Later films continued piling on new pieces of backstory, enough that the script for the reboot-necessitating sixth film drew heavily from writer Daniel Farrands' Epileptic Trees about the prior films. In other words, that film merely took trends that had been going on unchecked for over a decade to their logical conclusion. John Carpenter, looking back on the franchise he created, stated that its downfall came the moment it started giving Michael motivation and Character Development, with this being a big part of why he regards his work on the second film's script as an Old Shame."... Michael Myers was an absence of character. And yet all the sequels are trying to explain that. Thats silliness — it just misses the whole point of the first movie, to me. Hes part person, part supernatural force. The sequels rooted around in motivation. I thought that was a mistake."
- As for the remake continuity, one of the most polarizing things about it was in how it gave Michael a definitive origin story explaining why he became a killer, revealing it to stem from Abusive Parents and growing up in a broken home. Many who disliked the film saw it as a return to the Original Sin and a misunderstanding of what made the first film great, though there were also those who enjoyed the new spin that Rob Zombie put on the series and how it drew from real-life Serial Killer mythos.
- The much greater physicality of Michael Myers in Zombie's films also drew criticism. The stuntmen who played The Shape in the first two films, the 5' 10" Nick Castle and the 5' 8½" Dick Warlock, were fairly normal-sized men who didn't have much of a height advantage over the 5' 7" Jamie Lee Curtis; their subtle-but-imposing presence came down in large part to both men being strongly built and great at playing an Implacable Man, which made them seem bigger than the majority of Michael's victims (especially in the first film). Zombie, on the other hand, cast the mammoth 6' 8" Tyler Mane in order to make Michael more directly imposing and threatening, especially when paired with the 5' 3" Scout Taylor-Compton as Laurie and the five-foot Danielle Harris as Annie, which a number of fans felt took away from his Badass Normal image and turned him into a clone of Jason Voorhees. This trend towards making Michael bigger actually began with the fourth film, Halloween 4: The Return of Michael Myers, which cast the 6' 2½" George P. Wilbur as Michael; every future Michael would be at least 6' 1". It was even more jarring in this case, as it created canonical issues with how Michael grew so much taller between the second and fourth films* — and when the sixth film tried to answer that question, it became a major Voodoo Shark moment and a big part of the reason why the producers hit the reset button with H20. The fact that Zombie's films had Michael be outright gigantic and paired him with much shorter actresses playing his victims simply put a much greater spotlight on the issue. Again, the 2018 film defied the trend, putting Nick Castle back into the role.
- On a more minor level, Halloween: Resurrection got a lot of flak for, among other things, its Stunt Casting of Busta Rhymes as a cool, street-wise Action Hero who manages to put down Michael Myers — twice (once verbally without even realizing who he really was, and once physically) — and live to tell the tale. Halloween H20: Twenty Years Later also featured a rapper in a prominent part, but LL Cool J's role was substantially smaller and less over-the-top than Busta's, and not nearly as controversial as a result.
