There have been various comments here about the song that Holly sings, all positive as I recall, so some proper identification is in order. It is in fact called "Holly" (not "Only in Hollywood" or anything else), and was originally recorded by the band that wrote it, Republica, on their self-titled 1996 album. I would say that the original version as sung by the band's little spitfire of a lead singer is somewhat better than this movie version (though there's nothing particularly wrong with the latter). Although Republica only had their 15 minutes of fame here in North America (maybe a half hour in their native UK), they might be familiar for their two hits "Ready to Go" and "Drop Dead Gorgeous". The movie itself is formulaic (it was clear to me all along who the "dark presence" was), but the SF theme is interesting and FX are indeed good.
