I just reciently (last week) discovered and started watching this show as I found a dvd set of the entire 1st season at a Costco store. After watching the entire 1st season I did a web search and downloaded and watched all the rest of the episodes up to the present time. The only real "issue" I have with this show is in either the 1st or 2nd episode (not sure whitch one). Its where they go into the bank vault and jump about 8 years or so into the future and at the same Sarah blows the Terminator to bits that was after them. Its allways been my understanding that only living tissue can go..no weapons, clothing, etc. and the only reason a Terminator (metal) can go is because it's covered by living flesh as explained by Kyle Reese in the origal movie and also by Cam in the present series. So how did the bare metal head get through the time portal? At first I thought it was just laying there next to the freeway for 8 years whitch seemed kinda silly that it hadent been discovered in all that time till when the road worker found it, but after watching it a few times I noticed that Cam stated that it accedently came through the portal with them. Any possible ideas how this hapened? or was it an "oversight" ont the part of the writers? either way I think the series is great and hope it will continue, just wondering about that.
