I kinda felt the same way that some others felt about Sector 7, with them being a little unnecessary. But then I realized without Sectory 7, we would not care as much about Bumblebee. I mean sure we care about Bumblebee but when he was caught by BB under the bridge, I couldn't help but feel bad for the poor guy. It was like Johnny 5 syndrome all over again from Short Circuit 2. Turturro's character was WAAAAY over the top. A little bit too much for my tastes. Kinda distracted from the seriousness of the situation. But I think Sector 7 was necessary to for the development of other characters, namely Bumblebee.
