Mothman (2010)

Graduation is fast approaching and a group of teens is hanging at the lake, drinking and having fun.  Well it would be fun if they didn't have to babysit Jamie, Jared's little brother who is a couple years younger.

When they decide to scare Jamie and play a prank on him, he accidentally drowns.  The group decides they don't want to ruin their own lives.  So they come up with a story that he hit his head and drowned. Argh!  What is wrong with these people? And Jamie's brother goes along with it? What a tool.

To seal the deal, they each hit Jamie in the head with a rock, which is incredibly stupid as it's not going to look like an accident with six hits to the cranium. But apparently either there was no autopsy or the medical examiner is incompetent because they get away with it.

Ten years later Katharine, who is now a reporter, is sent back to town to cover the Mothman festival.  So I guess she isn't a good reporter since that isn't the type of assignment you'd give a serious journalist.

After running into her ex-boyfriend, Katharine reluctantly meets up with her old friends and discovers she was the only one who ever left town. Coincidentally it is ten years since Jamies death and the old gang gets together every year to toast Jamie.  A very odd tradition since you would think they'd never want to think of that horrible night they accidentally killed someone and then bashed his head with a rock to make sure everyone kept the secret.

Within a day of her arrival, members of the group start getting killed by the Mothman.  The police have no idea that it's a supernatural being. Because no one really believes in the Mothman. It's just a  harmless legend. Not so, says the creepy old blind guy who claims to have scratched his own eyes out to avoid being killed by the Mothman.

Intrepid reporter Katharine and her high school sweetheart Connor pursue leads as to why their friends are dying and how they may avoid the death sentence themselves.  The blind dude tells Katharine that Mothman can only come into their world through reflective surfaces, and Katharine notes there are no mirrors in his home.  Someone should tell him that he's wearing glasses and his house has windows because glass is reflective, dumbass.

Turns out Mothman only kills those who have killed others and hidden it to avoid paying the price.  So basically, he's a good guy getting justice for those have been wronged.  This leads us to the big problem with this movie, which is why would I care that he is killing these horrible people?
