I hated it. Light was smart enough to realize that all the people he used made stupid mistakes on their own, and as such, the cleanest (lol, not really) method to kill Near and everyone on the investigation teams would have been to cause Matsuda (who was obviously emotionally unstable) to start a fire fight. All he had to do was write out a detailed description of said fight in advanced, considering he knew the exact date and time of the meeting. Even if he had managed to kill the investigation through heart attacks like he planned, the police would probably infer he was Kira based on the fact that he was the only surviving member of both teams.
That's just my two cents, it was a great series other than that.
