A lot of films over the last few years are such utter crap with exceptions every now and again. Very few good films are made these days because time and again they have to make money, unless it's some sort of artistic thing like Glegarry Glenross or working for Robert Altman doing things like Gosford Park etc etc. You have to pander to the lowest common denominators in just about anything these days otherwise you kiss goodbye to 95% of any type of consumer - that's why there's no taste anymore. You can't make money with good taste. Just look at the way people dress - for Christ Sake - do you think that someone who can't dress themselves properly are going to understand what constitutes a 'good film'?.
When you have these type of conversations you really need to split it into two sections - making money versus good taste that can only be brought about by a previously good education. Anyone can make money if that's their primary goal in life and lets nothing like good taste get in the way. The reason many overly intelligent people don't make any money is because of just that - they let their intelligence and ergo, conscience get in the way. And that's why Hollywood in particular has no compunction in turning out crap most of the time. Let's face it - we've have 70 years of f***k***war movies alone. So film music is really so unimportant nowadays because it's generic and sounds the same - that the answer really is in the question posed a the start of this thread.
On a positive note - I like the Swedish original of Wallander for tv (the English version is shit). Not especially original but somehow very relaxing. And the score (I have no idea who did it) is not in anyway overblown and works perfectly.
