Don't get me wrong they're not overly bad (I mean I bought the first two when they came stateside and plan on buying the last two when I get the money (or if it's on Rightstuf's Black Friday or 12 days of Christmas sale)) they just weren't as good as the original movie or the SAC series's and movie. It was such a huge departure from what made the setting and the character's so enjoyable (I mean the Major just rubs me the wrong way in the OVA, she's just not as awesome as she was in the original movie or the series). It was like they decided to just take the framework of the story/background and the characters basics information from Shirow's original manga and throw everything else out the window (it's not like the movies and the SAC series/movie didn't do the same but they were more in line with what they were in the manga (and believe me the manga is completely different from the original movie, they took a lot of liberties when they adapted it)).
The Arise movie however was amazing and I actually enjoyed it, it really went back to what made GitS what it was (I really need to buy it). The Major actually seemed like the Major and while the other characters still irked me (Ishikawa was probably the only real character I liked in Arise, he didn't really change much) it felt more like GitS than the OVA's did.
(Honestly don't know why I didn't cover this in my earlier post but like I said these 10 hour days are slowly melting my brain)
