The build itself is good fun, as it should be, and engaging enough to be interesting. The only thing that I started to find a little boring was the Airport Control Tower, but then its top redeemed it. Naturally, the best thing to build is the Giant Man figure. The techniques used to make it posable, like a regular Lego minifigure, were brilliantly thought out. I hope to see more like this, perhaps in a Galactus set, although I doubt that’ll ever happen.
I like the nod to the classic LEGO Ideas Book with the 'Follow Me' sticker, but overall I think the F-18 type jet is redundant, making the whole thing over-priced. Had it been presented in a different colour scheme from the Viggen, and maybe a bit of a sleeker or more agile design in itself, it might have been a worthwhile inclusion. But as it is, it just superficially looks like two fairly similar aircraft, and thus quite a bit less value for money as a set.
I would also have liked a proper Ant-Man minifig – we get a micro Ant-Man, Giant-Man but not a regular-sized Ant-Man. There is a minifigure-sized Scott Lang hole in this set, and I think LEGO have wasted a great opportunity inserting a really popular and coveted minifigure into their flagship Civil War set. I would even gladly trade Cap and Bucky for one Ant-Man minifig.
The remainder of the build is the control tower and terminal building. First there is a metal detector screener leading to the waiting/secure area of the airport, which seems taller than it needs to be for the minifigures. I think the same effect could have been made with half the height, except that would not allow for an impressive height for the overall tower. However it does seem to be similar to many modern airports with the high ceilings. This area also seems to be someplace to check luggage as evidenced by the rather nifty conveyor belt that comes in a full part. The moving parts of the set include a revolving door (a very tall one, for the first floor) that leads from the secure area of the airport out to the tarmac, and of course the conveyor belt.
