Everything is relative with new figure releases. And this new Endor Han Solo is no exception. Compared to the previous Endor Han Solo which was originally based on the VTSC figure? This new one is a massive improvement. Is it what a lot of people hoped and dreamed for? Not completely. But I have to sometimes take the stance that perfection shouldn't be the enemy of a good figure.
Usually I'd be on the understanding side... but as a Han Solo figure stan, I think he deserve NEW at this point and not 'kinda new but mostly recycled'.
Like Rob said, I'm much more tolerant of these reuse/kitbash figures if Hasbro is making Jabba background guy #14 who we're happy to finally get after 40 years. When they do it for Han Solo, it just feels cheap. Yes, this version is better than the 15+ year old sculpt they keep trotting out, but that's a really low bar. A version with ALL-NEW legs with rocker ankles and better hips would have been ever better.
Maybe I'm just salty that every carded TVC Han figure since that 2018 TVC SOLO Han has been a repack/kitbash figure - photoreal updates to old TVC sculpts; repack of 2014 Black Series Carbonite Han, new head on old body ANH Stormtrooper Han, and now this kitbash ROTJ Bunker Han.

Sorry. Maybe Hasbro will make it up to me with an ALL-NEW ANH Smuggler Han in the near future.
