I am not a huge horror movie fan but for some reason I have always liked the Halloween movies. The first two were obviously very low budget and somewhat cheesy, as all the best slasher films are, and as you move on in the series they steadily get higher budget and such. What I liked about Rob Zombie's remakes was that it explained more of Michael's backstory which made him more human and, in a way, scarier than the cheesy boogie man he was before.
OP, for my money, Halloween I and II are good, skip 3 entirely, maybe 4 but after that it gets really hokey and I would just skip right on to H2O and go from there.
For me, the story is about Michael in an epic battle with Laurie. If she isn't in it, it isn't a Halloween movie for me. This crazy side story of Laurie's first daughter Jamie having a psychic connection with Michael may appeal to some but doesn't do it for me.
