I think the Star Wars forum here would be a little less off-putting if people could manage to be a little less hyperbolic.
The number of times I've seen the phrase "this looks nothing like so-and-so" or "there's no resemblance to the actor at all!" is a little bit silly. I guarantee that if you took this Obi-Wan headsculpt, (or the Han or whoever) to a convention, set it on a table and asked passers-by "can you tell me who this is?" they wouldn't have any trouble identifying the character. Nobody would look at this Obi-Wan and say "uh.. Colonel Sanders?"
So there is a resemblance. Now, you can certainly argue that the resemblance -to-cost ratio is not quite close enough for you, and that it could be improved.
But I see people here denouncing the idea that a figure has ANY redeeming qualities for reasons like "Vader's dome is 00.212mm off scale! This figure is garbage !" and, speaking personally, it can be a real detriment to any desire to join in a discussion here if you don't share those particular criticisms.
The bottom line is that if you don't like a product , the most powerful statement you can make is to not purchase it. But pushing past "It's close, but they didn't quite capture the likeness perfectly" into "this is laughably horrible, what a pile of ****!" can only be viewed as a need to reinforce that your choice (not to purchase it) is the right choice. But consequently, that simultaneously sends the message that anyone that does choose to purchase it is wrong /stupid for doing so.
