Ok, I am no Stelios, so I won't be really reviewing... I'll be commenting haha..
Monster House was a very well done movie, with a beautiful 3d work in it, a nice plot, nice characters, etc... but for sure it wasnt kiddie stuff... I mean I am 23 and I enjoyed it, and even got grossed out a couple of times, so go figure the smaller ones around me!!!
While watching the movie kids in the cinema hall were crawling to mum or dad's lap, and saying stuff like "I don't like it", "Why did she die mum?"... etc... Not something you want to offer to your own 6 year old child...
Beyond that point, it was an interesting 3d movie, specially since it didn't come from Pixar or Dreamworks... With a Halloween theme, released a bit too early to me, our 3 protagonists (3 children of course) have an obscure haunted house experience...

But this is no normal haunted house, its a MONSTER HOUSE!! Yes, the house is alive!! And if you think I said too much so far, let me say you find this out right from the beginning... The real secret juice of the movie is in the why of the mounstrosity!!!
The neighbourhood they move in is cool, even tho it's always the same blocks... And regarding to the characters, most of them look cool from some distance, but when the close ups come, you see its no shrek... I mean, its not in that level... That's why ey! we thought this was a movie for the little ones!! It looked for sure like one!! But then you start watching, and in the beginning of the movie the parents -that can't stop arguing- leave the kid with a adolescent babysitter, that is half dark, half a pain, who calls her bf over... and of course, he's freaky scary (and drugged up!!)
Back in those negative points, the movie wasn't just scary for small children, but is a bad influence!! The children act alone, and do lots of "don't do this at home" stuff, that really wasn't necessary for this movie to be interesting...
What else can I tell you? be ready for a "tolkien-resembling-character"!! Yeah... someone in the first half hour of the movie will look resembling amazingly to a tolkien character!! Check it out and let me know!!!
One thing is for sure, you won't fall asleep while watching the movie, but hey, you may consider first puting the kids to bed!!!
