H5 isn't bad, nor is its mask. It was a mess, but what you get in its final product, is a movie that H4 was missing: subtle execution, creepy atmosphere, all relating to the first film, oppose to remaking the first film which H4 went for.
And yes, I prefer the producers cut to H6, which regardless of which version, I still wanted to see a conclusion with 7. I mentioned this, but without any details, so let me explain: I would've wanted an H7 that concluded the Thorn series, brought back Jamie Lee as Laurie, and ended the franchise (for the time being) right there. I could see it working as with DP gone by that time, Loomis could've been still in the movie, hidden in darkness, and being a shadow of his former self as he is now in control of Michael. Tommy & Kara are trying to stay away from Michael, but they need information from Loomis regarding him, so they have to come back to his home. Its there we get the big reveal: Laurie was in a car accident, but she wasn't dead, that was fake; she's actually in a coma, and secretly away thanks to Loomis, and this works with the canon starting in H4. If you remember, Loomis knew Michael was going to Haddonfield, but until he went to the Sheriff's office, he didn't know about Jamie. For what he knew, Loomis thought Michael was gonna terrorize the town (better idea than continue the family angle IMO), or still looking for Laurie. Now that they knew, they go see her and see how she is; problem is, Michael knows too, thanks to Loomis. Both parties go there, and just as the tension goes into high gear, Laurie wakes up, finding herself in the present, but still stalk by her nightmare: Michael. After escaping, and trying to get herself back together, and Laurie dealing with her daughter's death in H6, Tommy figures out the best way to destroy Michael is from his family member, aka Laurie. After some convincing, Laurie, Tommy and Kara go back to Haddonfield, and face Michael and Loomis, destroying them both. Obviously, from H20, Laurie beheads Michael, ending him once and for all. The day is saved, and reign of Michael Myers is over. But in the final scene, Laurie, still dealing with the events, is still keeping Michael's mask. Why? Maybe because Michael is dead, but evil never dies, it just spreads...
That's my H7.
