As far as LEGO games go, this game is definitely... well, a LEGO game.
What I mean by this is that if you have ever played a LEGO game in your life then you already know everything there is to know mechanically about this game. In my experience, LEGO games are not so much about ground breaking, innovative gameplay; but rather, immensely enjoyable fun for the whole family that comes in all kinds of assorted flavors. Personally, I find the Star Wars flavor to be the best out of all of them, but for the same reason that a die-hard Harry Potter fan would tell you that the Harry Potter LEGO Games are the best.
Overall, if you haven't ever played a LEGO game, then don't just buy the "latest and greatest". Buy a flavor you love, and I promise you won't be disappointed :)
