i finally got around to watching THE SHIELD season 4 on dvd, and tonight I came across something very strange on disc 3. the entire 3rd episode on the disc (the exnteded episode), and the "Previously on the Shield" segment on that segment were presented in 16:9. And they looked great. i got excited that maybe last season they switched to 16:9 halfway through, but unfortunately the next episode went back to 4:3. I was troubled by a couple of things - first, that they'd shoot only the special extended episode in 16:9 and then switch back to 4:3, but then it occured to me : the "previously seen" shots from earlier in the season looked great in 16:9, almost like they were composed for 16:9 (didn't look zoomed in at all, and it actually looked LESS grainy than the Shield usually looks) and i started to think that the entire show was shot natively in 16:9 and preserved that way in some capacity, just not released in widescreen on home video. any reason for that? there were many times this season where i felt the shots were cut off on the sides...i dont' remember thinking that during the previous seasons....many times, a character is talking and their face is half cut off outside of the frame, and before the show seemed perfectly framed at 4:3. anyway i was just mad that apparently the whole season could have been presented in 16:9, and it wasn't. the 16:9 episode retained the grimy, immediate look of the rest of the show and enhanced its immediacy.
