I've never watched Ben 10, so I'd like to think I'm fairly neutral towards them. However, I'd much rather by a Bionicle set than these. They at least contain some useful parts.
I suppose I'm not in the demographic for these, and that's fine. Still, I remember getting, as a child, a cool robot set
that was made entirely from System elements. Heck, even the recent Exo-force
line was able to use System elements to create highly posable action-figure type creations. I don't understand why they can't create high-quality, action-figure type sets from the existing array of System elements.
Plus, I have to imagine all the sets required new molds for their unique pieces. Maybe it's just me, but I just don't get the point of creating a single, one-shot piece for a single set when you could just as easily create something similar with existing pieces. If it was a piece that could be used for different sets and really added to the System library, I'd understand, but these pieces add very little.
In the end, when I look at these sets, I see very crappy parts/part usage and no minifigs. Thus, there is no reason for me to buy them. Maybe some children will get a kick out of them as action figures, but I don't see too many collectors/builders wasting their time/money with them.
