Not all action figures are created equal. Some are amazing, and others...not so much. But the worst of all IMO are the ones that look like they're going to be great, and then turn out to be kinda meh. Not even necessarily awful, but nowhere near as good as we hoped.
So what figures have you bought that you either regretted buying or were just let down by?
For me, I'd pick Bring Arts 2B (1.0, I don't have the 2.0). She's a bit...eh. The articulation is decent enough, with a really nice mid-torso balljoint and generally good range of motion, but she feels a bit...rickety? Her stand is FRIGHTENING to assemble due to the tolerances, her joints are either too loose or too tight and the paint is variable; the skirt in particular has really sloppy drybrush work on it that looks like it belonged on a ToyBiz Marvel Legend. Worst of all, it only comes with Virtuous Treaty, which sucks as 2B always has two weapons with her in the game (though the sword itself is nicely made).
The saving grace is Friedrich, AKA Bucket Boy, the Machine Lifeform (from the beginning of 9S' story mode) that comes with her. He's awesome.
