I watched a rental copy of the Blu-ray version last weekend with my wife, who is not a fantasy/sci-fi movie fan, and even she liked it. It definitely has the "Saturday afternoon matinee" feeling of similar movies of my youth (now there's a dated memory) but was an improvement, effects-wise, over the 70s original (and I am a big Ray Harryhausen fan). I agreed with this and other reviews that some of the casting could have been better (Liam Neeson as Zeus was a miss, but Ralph Fiennes as Hades was closer to the mark and Worthington was a more than passable Perseus), but the effects, not the cast, is really the centerpiece of this movie, so the miscasts are easier to overlook than with other movies, IMHO.
