I liked it. The rathtars are pretty cool little builds. The rest of the structure is pretty standard as far as building goes. As far as playability for kids goes, you can interchange the modules (there are three of them) and there's a trap door for a minifig to peak out of. Two of the doors can be rigged to drop open or closed.
But the set really shines on display. The minifigs have a standard expression and a panicked expression so you can pose them in action. The two guavian death gang guys are pretty much in the set specifically to put in the rathtars' mouths and the effect is hilarious. Personally I like the color combos as well.
Negatives: the Han and Chewie figs are the exact same ones from the Falcon.
I would recommend the set for big TFA fans.
Thank you for recommending this set! I really love it. The modular aspect is just fantastic. I shouldn't but temptation to get another one is great. Only negative thing is that they come with stud blasters.
