Despite solid sculpts and an interesting array of characters this set still somehow falls short in playability.  There may be a nice variety of characters, but most are a bit bland or generally uninteresting.   That's not to say there are not good figures in the set.  Kypto, Batman (Thomas Wayne), Mister Mxyzptlk and a solid 200pt Wonder Woman.  Not to mention the Colossals that introduce the Colossal Retaliation ability.

So good try, but not quite.
