Gary Oldman is the best Dracula I've ever seen. Period. He steals every scene he's in, to be honest. Anthony Hopkins provides an amazing performance too, as the seemingly off-kilter Prof. Van Helsing. It's also a very visually-impressive movie. The film's main problems, however, lies in its uneven 'experimental' special effects (experimental in the sense that the film-makers went back to using old fx techniques), which are sometimes amazing, and other times cheesy; and Keanu Reeve's terribly fake British accent, which he puts to 'good' use by reciting some wooden lines every now and then. The script was okay, I thought; it could've used some touching-up here and there, but was overall decent.
So do I recommend seeing it? Absolutely. Just because it's not the best film out there doesn't mean it's not exciting and entertaining. If nothing else, you at least have an excuse to sit inside on a rainy day and curl-up with a nice horror movie.
