Just a terrible movie.  Quite possibly the worst Uma Thurman has been involved in.  Rating it on its own merits, it's not that bad of a movie-- just kind of silly and dumb and totally forgettable.  Comparing it to the Peel-era shows is what makes this very hard to watch.  First of all, Uma Thurman looks nothing like Diana Rigg.  Jessica Biel would make a much better Emma Peel.  Secondly, this is set in modern day.  So much of Peel's persona has to do with how she twirls her flip or wearing those white gloves.  Without that hair and clothing goes much of the essence of Emma Peel.  Sealing the tomb is a barrage of crappo CGI which makes the whole thing look like the graphics on a fast food cup set to motion.  For a dumb film of a similar flavor which actually succeeds at being a comedy, just rent "Austin Powers".
