Yes, I know I promised just last episode that I would watch H50 live on Fridays from now on, but that was before Grimm decided to air back-to-back episodes for the mid-season finale with Alexis Denisof and Krampus. It's not my fault! Maybe next episode.
Meanwhile, I'm not really sure what to say about this episode. I usually blather about the Five-0 characters and their stories and relationships, but this episode was very much a historical drama telling David Toriyama's story. It was a terrific episode, but I'm just not as invested in David Toriyama as I am in "our" characters. And my stupid brain had to go and spoil the ending by wondering who David Toriyama was going to give the katana to. It's been in his family for hundreds of years, but there's no one left but him now. The rest of his family is all dead.
I'm not surprised that Steve's grandfather came up, since it was established in canon ages ago that he died during the Pearl Harbor attack, but did he have to know the Toriyamas? Does everything have to tie in to Steve in some way? When Steve started going through his grandfather's things back at the house, I half expected him to find the katana under the floorboards or something.
The show went all-out on the historical sequences, though, especially the attack on Pearl Harbor. That was very well done. This really was a great dramatic episode. It just wasn't really a Hawaii Five-0 episode. If only the writers could crank out stories like this for our characters.
