Today on Sci-Fi Adventures I'm in the middle of In the Beginning, which is either the first, second or third of the Babylon 5 TV movies depending on who you ask. It was definitely filmed after The Gathering and Thirdspace, but it was the first movie to air on TNT to promote the launch of the fifth season.
This is the second part of a three part review, so you should probably start with PART ONE if you haven't read it already.
You should probably also watch the movie yourself, though make sure you watch four years of the TV show as well. Some would make the argument that the movie is actually a good place for new viewers for start watching the series, but I'm going to be dropping SPOILERS for seasons 1 to 4 and I don't want to ruin anything for anyone.
