As far as mini-figs goes, this is a good set if you skipped the UCS Slave 1 ( even if Boba-Fett isn't as detailed in this set, it's still a pretty good mini-fig ). The Ugnaught is a nice little exclusive addition to this set and can never get too many Hans
The biggest flaw in this set is obiously the build; the play features are awkward and not really that accurate to the source material. However, the stairs of this set can be detached, and attached on the upper platform, which leads me to think that maybe ( In my dreams probably ) that lego could release a bigger Bespin set to which you could attach this model to.
Overall, get it if you skipped the UCS Slave 1 and you like the mini-figs, but I'm having a hard time seeing the value with the build itself. But that's only my opinion :P
Hope this helps!
