I heard several cues of The Arrival and I understnd Mike's point. Not all music (and budget) for film has to employ a 120-piece orchestra, who said that? In fact I recall one of the most powerful and apt soundtracks I've ever heard was Joe Lo Duca's to the original Evil Dead. Another is Eyes Wide Shut where a single piano note or two suffice to create/complement a complex emotion and effect (although it is temp music from Ligeti). This Arrival thing did not impress me much as absolute music but it could be perfectly suited to the film, much like Nyman's to Gattaca (meaning the music sounds not too impressive if you have not seen the film). The visuals and music go so well together in Gattaca, that both media gain additional dimensions - that's how the magic happens and that may be the case with this Arrival film.
I know and respect some earlier Hans - say The Last Samurai - but any melodies of note, none I'm aware of (Gladiator has a theme, not a melody, and it is Vangelis' really). Otherwise, if Hans can only score stutters for any and every kind of subject and genre that he is given, that's not a style anymore, but charlatanism instead. As far as the mega sound and whatever quality if any in the music he achieves, he has a lot of help so no credit there either.
Imagine how I feel about the apes...
