Carkoon- I really only bought Bib on an impulse buy (It was the first TSC figure I had seen), but I think this wave could've benefitted from some new characters. Doallyn, Hermi, and Hoover would have been great additions to this lineup. It did have some really nice main characters resculpts, like Han, Leia, and to a lesser extent, Bib, but still a pretty weak wave overall.
Hoth- I really like this wave, Veers was simply excellent, the Power Droid was also a fantastic figure, and the AT-AT Driver and Derlin looked great too. Far better than the Carkoon wave. and even the repacks (R2, Vader, Rieekan) were good choices.
Geonosis- Great mixing in a EU figure, albeit a hard to find one, and great new sculpts (Sora, Sun, Scorch). Some of the repacks were good choices (Poggle and 3P0), but the last couple of repacks (Jango N Yoda) were weak choices, and Jango could've used a resculpt.
Coruscant- An excellent wave, it had a EU figure, two requested figures (Cody N Fire Pilot) and good repacks. Lushros was exceptional, one of the best TSC figures next to Veers (Although I may be a tad bit biased 'cause I'm a Neimoidian fan).
