What's the top 3 ? (except this night lamp)
It's a hard one to judge I guess. I guess I wouldn't go too far back because earlier Hot Toys were relatively cheap and didn't have the same expected standards.
In the modern era of the top of my head (plus a little refresher), the most recent Batman Begins Batman would have to be in there, both the TV Show Flash figure and the movie Flash were pretty bad (anytime a 3rd party looks better its bad), BVS Wonder Woman was bad, the Force Awakens had some duds like Chewbacca and the articulation across the board with those figures, the Doc Browns maybe, 1/4 scale Joker was crap, Ultron Prime with the fact it only looked good with the lights on, the Johnny Silverhand was a terrible sculpt, Ripley was poor considering the wait (the Aliens Xeno wasn't great either with its mobility and QC issues), MK 85 Iron Man with its initial headsculpt, recently Mace Windu was pretty poor, smiling Ant Man was hilarious too.
I've missed a bunch I'm guessing, but it depends also if a bad headsculpt or a single QC issue is enough to push a figure into the top 3. I've got bad memories with a lot of figures but they're often largely down to one issue, whether its bad posability, a bad headsculpt, QC issues or irritating inaccuracies. I guess Hot Toys poor figures tend to fall into that category of mid but serviceable, rather than outright disasters.
