This movie is fast paced, well acted, well directed, and beautifully filmed. The action was exciting, esp. the device of setting up fight scenes as Holmes' did by walking through it step by step. RD, Jr. and Jude Law do great jobs creating enjoyable, interesting characters from two iconic templates that could be clichéd but aren't. Downey develops a fascinating Holmes, making his intellect and charm readily apparent, as well as his idiosyncrasies humorous and touching at the same time. Law plays a wonderful counterpoint, which I'm SO glad isn't handled as most other depictions of Watson as a bumbling oaf. The writers develop strong antagonists, still keeping the elusive Moriarty in the shadows. It makes a good foundation for a great sequel.
