First off, i will admit that I've never been much of a fan on shonen. Whether its anime or drama,I've always preferred watching romance. For someone like me, who only prefers romance dramas, i fell in love with this! Yes, the movie definitely changed some things from the anime. But what movie doesn't? Especially for anime, some things would look a little weird without changing it while doing the live action. And this way, you're not watching the exact same thing. I found both the anime and the movie very entertaining, and i recommend both. The acting in this was also really great! The actor who played Light was very impressive, I could see where he was coming from, and what type of personality he had easily. L was played really good too! I'm team L all the way, and never once was on Light's side! So if your considering whether to watch it or not,here is what i suggest: if you are an avid anime fan keep an open mind that there are changes to the movie. If you've never seen the anime, i suggest watching that first. That way the movie won't spoil you with what will happen. Or vice versa. Whichever you prefer. Hoped this helped!
