You’re certainly entitled to that opinion, but as a big fan of the book, I completely disagree with you. In particular with the first film which I think is one of the BEST adaptations of a Stephen King book.
Like Lord of the Rings, it’s not about how many things they take exactly from the book, but capturing the SPIRIT of the book, which the first film has in spades. It just oozes with atmosphere and character and certainly captured the feel of the book to me. I would tend to agree with you that the second loses that a bit, though I still like it.
And for the record, I hate the miniseries - other than Tim Curry. That was something that completely missed the tone of the book IMO.
I think we'll just have to agree to disagree. But I think what hurts the movie is how rushed it feels. The dinner scene, for example, is a huge scene in the book, but it takes all of five minutes in the movie. I get that this is a movie, and we can't spend as much time in any one place as you might like, but there didn't seem to be any real set up. And the movie bizarrely has the characters forget
everything, meaning Mike has to then catch them up, but it's all done so poorly.
The tone of the scene is all over the place, and I think it's biggest problem might be that it's constantly trying to interject humor. Making Richie try to crack up the characters in understandable. Making Richie try to crack up the audience, however, just undercuts the tension of the scene. But the movie always ends up doing this.
While the mini series certainly isn't great, I actually felt it was much more in keeping with the tone of the book, and the spirit of the characters. Partly because it was able to introduce the adults early on, giving them enough time to come to grips with the news It has returned. Which plays a big part of the real horror of the story. The characters know how bad things are going to be, but return anyway. With the movie, they don't remember anything, so there really isn't the same amount of dread.
And just compare these two scenes of the Losers finding out about Stan's death
In the movie, the characters are more concerned about their own safety, than the news their childhood friend just commited suicide. They then berate Mike for not telling them the truth, and decide to leave town.
In the mini series clip, we see characters actually enjoying their time together, and being suitably devastated by the news. We see Ben go to confort Mike, and Richie toss the phone in anger. The scene works because it actually makes sense, and characters behave like how people would behave in real life.
