The only way to see season 1 of ANGEL in widescreen is on Hulu.com, and now they no longer have every episode (though through a series of shall I say, 'creative' means, I personally captured every episode of it that way)
It has the same overall look as widescreen Buffy season 4, where the errors created by the expanded frame are more apparent than in season 2 / Buffy season 5, and has a softer image compared to later seasons, just like Buffy.
I have screencaps of season 1 in widescreen, as an addition to the caps I made above:

It's titled "season 2" but there are a lot of season 1 caps in there.
Also, "City Of" was not expanded correctly, so it is expanded on the left side only, and therefore stretched to make it fill the 1.78:1 shape. The only way to restore it to its original shape is to squish the image until there's a black border (like a 4:3 border on a widescreen TV) on the right side only. Eagle-eyed viewers will notice a black border on the side of a brief clip from "City Of", as shown in the title card for David Boreanaz in the season 3 and 4 credits - it's the first shot with is name.
I've been on an ANGEL rampage lately, which is why I noticed the bumps in this thread. I've been making a video project, attempting to create the same overall feel of the original broadcasts, with WB trailers and recaps re-attached to the episodes. Silly? Perhaps but I truly love this show that much so it's worth the time and trouble to do it.
