It's entertaining, but without Light or Misa (my god she was hot!) or Ryuk the whole thing is disappointing. It's like if there was an episode of "Buffy" starring only Giles. Honestly, if you're a big DEATH NOTE fan I would just skip this film, it's just going to disappoint you. As a stand alone film it's OK, but still boring. Skip it.
I guess I could tell you the plot: L has to stop some terrorist from releasing a deadly virus that will kill everybody on the planet. Of course, if he didn't burn the Death Note at the beginning of the movie he could just kill them. Then again that would be against L's morals.
