I think Clemmenson appears to have a problem with Newman's 'wacky' side. So he uses some interesting instruments and some different methods from other composers - he should be applauded for this, for creating a very American but also emotional atmosphere (Fixture Vodka & Sleepover to name two tracks).
I haven't seen the movie, but having seen a one with a similar score (Erin Brockovich), I know that it will fit it like a glove. I urge people to give this score a chance and not judge it purely by Christian's very closed-minded approach.
Sorry Christian, but this style does work and I don't think it has anything to do with budget - watch the movie and think whether it needed anything different.
