That's fair. I've certainly been disappointed on things on the first listen and grew to like them. I had assumed you had listened to it more than once by now
I had that with HP1... I now consider it a top 10 JW score. 
Not to hijack the discussion, but wow. No amount of listening could ever convince me that any of Williams's HP scores belong among his top 10. The underscore for the first Potter film in particular is among his most tedious for any action-adventure film, and, on the whole, the themes -- as many as there are -- pale in comparison not just with Golden Age Williams but with nearly anything he wrote between 1989 and 1993.
Well, it's at number 10. 
1. Star Wars
2. E.T. The Extra-Terrestrial
3. Schindler's List
4. Raiders Of The Lost Ark
5. Superman The Movie
6. The Empire Strikes Back
7. Jaws
8. Close Encounters Of The Third Kind
9. Jurassic Park
10. Harry Potter And The Sorcerer's Stone
Actually, mate, it's:
1 CE3K
2 Superman
3 The Towering Inferno
2 The Empire Strikes Back
5 Riaders Of The Lost Ark
6 J.F.K.
7 The Accidental Tourist
8 Empire Of The Sun
9The Witches Of Eastwick
10 1941
First off, let me say that I know nothing about responding to music on an intellectual basis. I am impressed by learned breakdowns of the score by people such as Incancus, but I listen to music with my emotions, and so I am unable to assess "TINTIN" with anything but my heart, and the relationship that I have built up with J.W.'s music over the last 37 years.
Also, I have not yet seen the film, so any comments I make are the result of me responding to the music sans images.
This score almost seems like J.W.'s valedictory work, as it appears to incorporate motifs and snippets from almost every action film that he has scored in the last 30-odd years. It's a curious mix of "ROTLA", "Jaws", "1941", and "Star Wars", which is no mean thing, except...I've already heard thsese scores. I very much like the first track, especially as he seems to reference "CMIYC" a lot, and is his most original piece in ages. I am afraid that the rest of the score seems to blur and melt into one very loud, busy piece. To these ears, there is a lack of themes, or put another way; it's not a score that I feel that I can whistle. It's all very kinetic, and reminds me of Snowy running around trying to catch his tail: there's lots of "stuff" going on, but it really doesn't mean anything. I'm absolutely sure that the score fits the film; it just doesn't make for a great listening experience. Am I dissapointed? Yes, but not as dissapointed as I was in "KOTCS", and for that alone, and because I WANT to like "TINTIN", I will persevere. Damn you, sirs; I WILL try!
P.s., Is the fast-paced music heard at the begining of the trailers composed by J.W., and, if not, then who?
