It's cool that they are making these, and I was expecting to be really excited about them, but after actually seeing them, my reaction is basically 'meh'. I was hoping/expecting them to look better than this.
Even though I never got them (and in hindsight wish that I had), the Mega Bloks TMNT figures/sets from a few years ago (based on the 2k3 show) just look A LOT better IMO...
.... and normally I feel that saying Mega Bloks are better than Legos is blasphemy.
I think a big part of it is the fact that the Mega Bloks versions actually had sculpted body parts as opposed to the standard Lego body with the details simply painted on. I know that's Lego's 'thing,' but there are times where exceptions should be made, and I think this is one of them. Even Mega Bloks' Shredder looks better with the sculpted body.... though I do like the bigger arm spikes on the Lego Shredder, and the head looks cool, too.
I might be tempted to get the new Lego versions if I could also find the older Mega Bloks sets for a reasonable price (but from some recent searches, they are going for quite a bit). Since the new Lego versions are more 'cartoony' looking, I could put them side by side with the Mega Bloks versions and have Lego Turtles Forever!
