Justice League vs. the Fatal Five

I wasn't quite sure what it was that bugged me about this movie at first. Then I realized that I didn't care. It wasn't so much a dislike of it as I simply didn't care. I didn't care about the characters. I didn't care about the plot. I didn't care about the stakes. I just didn't care. This probably has to do with there being little to no characterization. The new characters (Jessica Cruz, Starboy, Miss Martian, etc.) are given personality quirks instead of actual characters. Sometimes they get downright annoying. Who are these people? How did Jessica Cruz get her GL ring? Who is Mr. Terrific? Where did Miss Martian come from? All these questions and more...will not be answered and you just have to accept that they appeared out of nowhere. The plot doesn't get much better. The motivation for the villains? Seems to be little more than twirling their mustaches. The stakes? Unconvincing at best. All around, this had the potential to introduce new characters in interesting was, but instead trips over it's own feet coming out the door with sloppy, shallow writing.
