Let me get this out of the way first and foremost, "Ulysses" is, in my opinion, THE greatest novel of all time; it is a book I've practically worshiped within the past year and I believe that almost everything about it is brilliant, if tedious and difficult at times. "Bloom" is a competent adaptation of the source material, but, there really is no way to TRULY adapt "Ulysses" unless one was willing to turn it into an avant garde miniseries. There are so many aspects of the novel worth exploring, and most of these aspects aren't even touched upon in the film. However, as a film, "Bloom" is quite enjoyable and some sections of the novel are brilliantly and beautifully presented, particularly that of Molly Bloom's (in)famous soliloquy which closes the novel and the film. Angeline Ball pulls off Molly's hypnotic inner voice perfectly, and her voice is paired with a powerful, swelling musical score that crafts a sequence so rich in beauty it nearly matches the masterful words of Joyce.
The performances are mostly quite fantastic across the board. Stephen Rea is very good as the title character (the immortal everyman, Mr. Leopold Bloom!), although I do feel as if his narration of Bloom's thoughts was a bit too dramatic at points. Much of Bloom's consciousness delves into comical, bawdy, and ridiculous territory, and even when Rea is reading aloud lines of such a nature his voice remains soft and serious. However, in the more fantastical and blatantly comic later scenes, his performance does get as goofy as is necessary.
On all fronts, this is a respectable and beautiful motion picture.
