I loved the first 5 Halloween movies, and then this thing happened and the series never recovered from it and the nicest thing I can think to say about it is that at least it's not the worst movie in the series. In fact in a lot of ways it's like horror equivalent of Highlander 2, and just like that movie, I don't think any amount of lost footage or editing out the dumb bits could possibly save it.
All that being said I will still probably buy it at some point, because I bought both the Halloween Remakes and Texas Chainsaw 3d, so quality isn't something very high on my list of requirements for owning a horror movie. In fact the only requirements I have are 'see horror movie' and 'have money to buy horror movie'
