Why the butterfly effect 2 dots is too good like the first?

I love the 2nd movie. I orded in online and hope to get it soon. I check my mailbox every day hoping to see it. I love how they sorta tell the same idea but not someone horrible scenes that the first one. I hated the guy who liked seeing the kids naked in his private movies or the scene where they blow up the mailbox. I am glad part 2 don't have horrible scenes like those it just concentrates on the illness. I think its a interesting illness, but if I had it I wouldn't keep changing the past, especially if I noticed I was getting nose bleeds or other health problems.
