I've always thought that Lego and Transformers were a great mix. This years Kre-O sets got me very excited when I first heard about them, however I was disappointed when I found out that they were not truly transformable and were big ol' partsformers.
I've seen some awesome Lego Transformers, so it can be done. Hasbro's attempt with these are very disappointing. Personally, I find the designs poor and silly. At least for the robot modes.
I'm leaning towards a complete disregard of these. However, there are two saving graces for these new sets:
1. The Vehicle Modes Are Rather Nice
Some of them look fantastic. The rest look okay. If I were to pick any up, it would be for the vehicle modes.
2. The Minifigs
Actually, they're called Kreons. That link there takes you to a pic on Seibertron showcasing a bunch of these little guys. Turning to my experiences with Legos, I foresee that these will be really popular.
Maybe it isn't up to what I wanted, but as long as they're packed with those Kreons, I think that the new Kre-Os can do pretty well this year.
If I do get any at all, it'll be the big Optimus Prime. I think that one looks the absolute best.
