The problem is that Hitman games, fundamentally, shouldn't play like what I have seen in that video. But maybe it's just the tutorial level and the sandbox levels and the complexity are still there.
All the intro levels are like that in the Hitman series, so I think it's better to reserve judgement until we see some other levels.. Very Splinter Cell / Deus Ex though, although I kinda liked the takedowns, especially the "shhhh". Evil right there.
