Watched Insidious Chapter 2, haven't seen the first one but read a summary of it before watching it to understand the main details that seemed to be the only important knowledge before seeing this movie.
It surprised me that I didn't hate it (however probably not on my top 10 list), I usually don't like ghost movies, the ghost movies I've seen have tons of obvious flaws and ridiculousness, like a victim running somewhere in the house instead of just leaving the premise. Let alone, it bothers me to see most of them ending with an explanation for all of it, I have some imagination of the cause and the movie's explanation is extreme ridiculous like a six year old came up with it, but this one didn't disappoint me.
