As a fan of both Ghost in the Shell and Science Saru, I really hope this is good.
GitS is one of those series where I don't feel like there's a perfect or definitive version--each manga, movie and show has its own strengths and weaknesses on display, and they all indirectly contribute to a bigger picture of what the world and characters are all about.
My hope and expectation for this new show is simply that it adds its own contribution while doing justice to the characters, exploring the series' themes as they relate to today, and telling an interesting story that's fun to watch.
Yeah, I know what you mean. Personally I think a bit of lewdness should be expected by anyone who is familiar with the source material and Shirow Masamune. After all, this is a guy who has spent a big part of his career drawing semi-erotic illustrations, so it's fine for GitS to be at least a little bit sexy.
