First off, I have seen a lot of films in my time and this is nowhere near the bottom 100 in acting, plot, humour, direction, wardrobe, makeup, or anything else. Unfortunately, the sheer volume of votes by people who haven't bothered to see it means this review will probably get lost and ignored, but I think this film deserves better than it's getting so I'll try anyway.
I won't go over the plot because that can be seen above, except to say that its the usual love story sort of thing. I don't think the filmmakers were going for anything mindblowingly original here, nor is that what we end up with. What we do get is a sweet and lighthearted film that takes an everyday setting and throws in some fairly normal, although exaggerated, characters and builds a simple little interwoven romance around them. From the outset it's not difficult to predict what will happen in the end, the acting of Paris Hilton isn't what I'd call good but it's by no means teeth grindingly bad either, and the characters (especially June and Johann) have been taken to the extreme in terms of looks and talent respectively but that is no bad thing. The aforementioned things do prevent you from getting fully immersed in things and you're constantly reminded that you're watching a film, but I think thats okay for something that only wants to entertain you for a while. The other actors were good, it was shot well, and the script and narrative, however simple, were well matched with the cinematography and general feel of the film. The film made me laugh several times (which is more than I can say for most recent comedies), the interactions between characters was handled well and the ancillary characters neither infringed upon the main ones or felt pointlessly lost in the background, and the direction, whilst not world class, was better than I've seen in a lot of films and no shots felt out of place or jarred you from the flow of the film.
Overall, I found this film entertaining despite not being immersive or 'deep' and, since I believe that was the intention, I can't say the filmmakers failed here. I don't feel that I've wasted my time, I had no trouble watching this all the way through, and although I probably wouldn't watch it again for several years I thought it managed to lift itself above the usual standard of Hollywood films these days, if only a little. If you cant stand Paris Hilton, if you want to tax your brain, or if you want a film to get lost in then this is one to avoid, however if you've got some time to fill and you want to see something that wont weigh you down then you can't really go wrong with this one. There's far, far worse out there, trust me.
