Blackheart had its moments, but was mostly predictable. Maria Conchita Alonso did an excellent job. A much more interesting character than she has usually played. Richard Grieco also did well, but nothing spectacular. The other performances were adequate, but to be fair, the story didn't have enough going for it to allow the actors to do much but just go through the motions. Christopher Plummer's character added some levity that would have seemed awkward, but as the movie started to drag this performance became more appreciated. The movie grabbed me early with Maria's performance, but later the story became more routine and even Maria's character couldn't add enough interest to keep it exciting.
