Picked up Super Hero Airport Battle last night. Pretty cool set, but not spectacular.
The air traffic control tower is a pretty basic build. The only thing I learned from it is how the A-frame pieces like they introduced with the LEGO Movie stuff actually notch to the corners of angled wing pieces. That was a cool discovery.
The Quinjet Jr. was a nice little build, but felt lacking compared to its two older siblings. It does have a plethora of dark blue bow pieces in it, and the drop down guns are pretty cool.
It does come with a new piece type, which is a 2x2 angle piece. These are going to be very, very handy for MOCs once they start showing up in greater quantities.
The figures in the set are nice, but the leg prints, or more to the point lack of prints, makes half the figures look cheap. Thankfully, they didn't cheap out on the War Machine figure, as the print on him is fantastic.
The real star of the set, and the part I was most excited about, was Giant Man. It was so awesome making a massive mini figure. The nice thing is that for the most part, it is made of pretty standard and easy to find parts, so pulling off your own custom brick built big figs could be easily done. The only two knocks against it are that it looks empty without the stickers (I put them on, and it is leagues better then), and the entire back side of the figure is just exposed undersides of all the plates, so it doesn't look as good from all angles.
In the end, a very well made set, but definitely one to wait for a sale on. Now, if they put out Giant Man as his own set with some other tiny things for him to smash, then it would be fantastic!
