Like I said, it's a flawed comparison. The Efx is suppose to have lineage to the A New Hope helmet. But the original BS is based on it's appearance in Revenge of the Sith. This new Obi Wan version appears to be the same mask and dome, with a new neck piece.
I didnt really care about what the comparison video said, i pretty much fast forwarded through it to see the side by sides and such.. I was comparing these as props and not as toys.
Yes, it would be nice to see the actual props next to each other from the various series and films but i dont see that as happening anytime soon. For now, all we have to go on is designs based on the props, and we know those can be a bit on the "artistic liberty" side as most do not have true measurements from the actual props or even any access to the plans for those. There are countless examples of that.
If you are one who does these replicas, you generally have to take screenshots or photos of an actual prop and come up with a way to make measurements on those to get anything similar to the eye test. And we also know, the more you work on your own copy, the more you think it looks similar to the original even though it may be lightyears off when its finished to someone else who has not seen it before.
I'm sure Hasbro acquired some kind of paper plan or access to a prop at least for measuring or photos etc, to make some sort of a copy of that prop, and i assume they applied a bit of a reduction percentage to their copy for the mass public to buy for a particular price point. But from what i saw, they "toyified it" more than i thought they were doing on these BS replicas.
Take the XWing Pilot helmet for an example. Yes, there are differences, but the lines are very similar, the size is pretty close.. and true, it is a slight bit smaller than the actual prop... not much. However, when comparing those proportions, you find very little to gripe about.
I realize some of the things they did with the prop in Kenobi may have been embellished for the camera in certain scenes, for lighting, or for facial recognition or for cool factor... But you can be sure that the initial assembled vader was close to what was done in Episode 3 or even in the more recent Rogue One which Disney had control over as well. I cannot imagine that this BS helmet is closer to what was created in Kenobi than even the EFX helmet which was made from a different film. I could be wrong about that, but i have my sincere doubts. I just think the BS bucket is flat ugly when compared to the other prop.
Granted, its light years better than the old Rubies from when i was a kid, or from some more recent other toys, because for a toy this one is a cool Christmas present. But if the BS series is trying to base itself on accuracy of proportion, or whatever else they are trying to market themselves to adults other than a toy.. they failed in this one in my opinion.
Interesting question for the Hasbro BS line... do they start with a head sculpt at a certain size and hand form molds for the prop helmets they are making? Or is it all done in software form? Interesting.. would love to know.
