Death Note Rewrite is pretty much a recap of the first twenty-five new episodes compressed into two hours, with an alternate ending and a few minutes of new footage in the Shinigami realm added.
How much value you'll get out of it really depends on whether or not you've watched the series previously before going into this. If you're like me, and have seen the entire series leading up to this, then you'll find this pretty useless, except for maybe ten minutes out of the total two hours that's new footage, which is a pretty shit percentage. However, if you haven't seen the series at all, and are looking to get through the first half of the series in two hours instead of a half a day's worth of episodes, then this would be worth a watch, if you can figure out what's going on, as the recap doesn't really explain much.
Everything is pretty much the same as in the series, so I don't feel the need to reiterate what I said in my review of the series proper. Whether or not you get any value out of this "rewrite" really depends on if you've seen the show or not.
Hopefully, though, the next Rewrite will live up to its name and include more new footage.
