Cell

I have to say, I think Stephen King is a genius and I love his stories - but I do tend to go into them and his books and his films in a ready to run position.  When I say a ready to run position, I mean, with King stories, they can get a little weird and you never know what you might get.  Take the kids orgy scene as an example. 
I had never heard of Cell, as far as I knew, so I had no idea what I was in for, but it sounded good. "When a mysterious cell phone signal causes apocalyptic chaos, an artist is determined to reunite with his young son in New England.".

On the outside, this film looks good, it has a good cast, and what I would call, a good storyline, but as you get further in, it seems to be less pretty.  I watched it, not only because it's a horror film, (obviously), but because I actually was really pulled in by the storyline.  As soon as the evil phone signals took over though, I am sorry but I lost it.  It just was not done that well, the, (can you call them zombies..? They aren't the undead though..., let's say possessed.), the possessed aren't the most well done of characters, it's just done quite humorous.  It's not meant to be, but I feel it looked like it, just a lot of screaming and shaking and running into walls, with a fair bit of brightly coloured blood.  

I have to compare this film to The Happening, The Happening is a horror film, but is more humorous than terrifying, but in a way that it doesn't mean to be. 
Take for example, "What? Nooooooo", that's a funny scene, and it really is not meant to be.  There are parts in Cell where it is definitely more humorous than scary, such as how the group call to the big phone signals in the sky, looks more like they are trying to catch flies.  And mum walked in right at the end, when all the 'Phoners', (turns out that's what the possessed are called.), are running around in circles around a phone tower.  She genuinely said they looked like river dancers, and it was true, once I saw it, I couldn't unsee it!  It isn't that good a film so it didn't really ruin anything...

I also forgot some of the ending, and I've just used Wikipedia, and it seems like I got the ending completely wrong... whoops.  The ending is actually better than how I had thought it had ended, so that's something, still isn't that good a film though. 
I would say, if you want a Stephen King film, watch the new IT instead, or Gerald's Game... 

Oh, and I feel like it has a massive message about not using your phone too much, so TED talk, look up and stop using your phone so much.
