Last week I saw the new Jumanji in my local cinema's weekly sneak preview. (For those who do no know what it is: You simply buy a cheap ticket without knowing what movie you get to see. The movies are always movies that come out in 1 - 3 weeks)
And I have to say I really liked the movie, even though the only reference to the original is the name and a short scene at the beginning. (There might have been more references that I missed, but it's been a while since I saw the original.)
Now I looked online to see what others think of the movie. The comments that I found, from people that have actually seen the movies, seemed to like it, but the larger percentage of comments were from people who haven't seen the movie, who judge the movie without giving it a chance.
