Got a chance to crack open the three FF movie figures I found, and I really like all of them. I especially like the Human Torch figures (Series 1), probably one of my all time favorite action figures. It has a really nice likeness that comes through even though it is molded in translucent plastic, the articulation is quite good (39 pts), the joints aren't loose on my sample, and the action feature(s) are even kind of neat and unobtrusive. Right now I'd say if you picked up any of these, just for fun, this would be a nice figure to have.
The Mr. Fantastic figure is pretty neat too. I haven't gotten a chance to put all of the "extending" attachments on yet, but the ones I have used work pretty good and you really can't tell a difference between the "rubbery" extensions and the regular figure, so it fits together smoothly. I'm trying to figure out how I want to display him exactly. A nice figure overall.
I picked up the Series 1 Thing, even though I initially planned to wait for Series 2. I guess it was a combination of being excited to find them, and the fact that I think the likeness on this one might be a little bit better. The articulation is "ok", with his right arm and left leg missing ball sockets due to his action feature. He has a small tab on his back that you can use to make him swing to punch, and his fist and foot have a "smashing" sound to resemble a punch. On mine, they are quite touch, and really start to get annoying after awhile. I bet the kids will love it though. I might end up picking the Series 2 (or 3) version up too if I find them, but for standing on a shelf, this one isn't a bad figure.
I haven't found anything from Series 2, or Invisible Woman from Series 1 (checked again today, no go), but of these three figures, I think they are all pretty good. Human Torch is definitely my favorite, and I actually prefer it to the ML version I have. Hopefully IW (and Doom) won't be as impossible to find as it seems right now, I'd really like to have a "complete" set of all of them.
