That's the point though. Innocence questions whether or not you are still a real person when you become part machine, so the CGI was used to symbolize that and make you question if this world is real or not.

The show was weird for me. When I watched the first season, it just felt like the show was suppose to be 25 or 26 episodes long, but for some reason was cut in half to give use two seasons. I told my brother and after he watched the Garo anime, he agreed with me some what on how it felt.

From what I know the OG anime film was an adaptation of the 1989 source material manga and ARISE is the 4th iteration of Ghost In The Shell franchise, and is considered a re-imagining/reboot of sorts based on what I have gathered. The voice-over cast was re-casted, the art style changed, etc.
Fun Toku-related bit: Batou, the big guy with the small augmented eyes, was formally voiced by Akio Otsuka, aka the voice of Champ/Oushi Black of Kyuranger. He has been replaced in ARISE alongside the rest of the cast.

so is ghost in the shell arise reboot or prequel to the first film

From what I've seen yes. If you like Ghost in the Shell, check out other works from Masamune Shirow. Appleseed and Dominion Tank Police are both great in my opinion.

so witch is it a reboot or a sequal

Adaptation/reboot

Ghost in the Shell as an anime has three universes - Movie (Original movie & Innocence), Stand Alone Complex and Arise. All are unrelated from each other.

OK that new first time heard that. As when I was looking online people fan stated S.A.Christmas it inbteewn first and second due 1s gig set in year 2030 one year after first film while 2nd gig is set in 2032

I tried watching this show called Severing Crime Edge and I couldn't make it past the second episode. It was down right dreadful. It was like the show had an identity crisis halfway through and didn't know what it wanted to be. The animation was pretty lackluster and the music kind of sucked too. Not going to bother watching any more of it.
