The Innkeepers was fucking terrible.The characters were extremely bland,and the story,as you said was way too slow.Not only that,I found that the acting was pretty poor,and quite frankly,the movie wasn't very tense or scary at all.I also watched House Of The Devil,and while it was better,it was pretty piss poor too.I think Ti West is kind of a hack to be honest,and his movies have no real artistry to them.
Odd, I thought the characters were the only good thing about The Innkeepers. I really dug the chemistry between the two, but it wasn't enough to save the movie from a scare-less, generic, anticlimactic last act. The House of the Devil was a slow burn, but the attention to detail and the main character charmed my pants off. It truly felt like it came from the 80s. But it'll be a while before I revisit it.
I was also a fan of Ty West's installment in V/H/S, but it seems I'm alone there. I thought the acting and dialogue was incredibly realistic and the story was very basic and minimalist, but chilling.
I saw Rob Zombie's Lords of Salem over the weekend and I absolutely hated it. I see some die-hard fans (and even the guys from Red Letter Media...who I normally agree with) praising the visuals and their "psychedelic" nature, but I found the visuals to be stale and forced. Zombie's a legitimately creative guy, but this felt like he was doing everything he could to scream, "Hey, look at me! I'm weird and crazy! Look at me! I don't care!"
It was just 100 minutes of bad movie making, but I will admit that it looked like it had more than a 2 million dollar budget. And I'm always happy to see Ken Foree on the screen.
