While those inaccuracies are inexcusable, in my opinion, the scale of this model is undoubtedly striking. The figure measures 52cm in height and the biggest LEGO mech to date, comfortably surpassing even 21311 Voltron! In fact, the previous direct-to-consumer Hulkbuster, 76105 The Hulkbuster: Ultron Edition, looks surprisingly small beside its modern counterpart. There are obvious gaps between the waist and the upper legs, which might be understandable if the legs could move. However, they are static, so these gaps should have been closed. I like the texture on the legs though, including accurate metallic gold panels and some mechanical details across their front and sides. The proportional issues with this rendition of the Hulkbuster are immediately noticeable, as there are various areas of concern. The torso has been stretched, the head is recessed too much and the legs are too narrow, which spoils the Hulkbuster's stance. Taken in isolation, some sections feature considerable detail and look superb, but the overall model is poor. But in all seriousness, every review I have seen on Youtube, this thing looks like it is so top heavy and will topple over if they accidentally bump the table. It looks incomplete in a lot of places, and over-detailed in other places, making it look look bulky and bare bones at the same time, with some sections looking out of proportion. I'd rather celebrate winner Lego sets with the community, but that is becoming less frequent. The Hulk-diaper-buster is a loser, represents a bad trend for Lego, and I will not pretend otherwise. "

I always wonder how much say the licensor has in it. I mean, there have been a few instances (I think mostly with Star Wars, so also Disney) where Lego released a set before the movie was out, and it turned out their design was substantially off."

Manual

This set comes in an “thumb punch” style box featuring the logo of the Marvel Cinematic Universe catch-all branding, “The Infinity Saga.” The fully constructed figure appears hovering in the air, with his palm-mounted repulsors ready to be raised for battle. Stark wore many, many different armors during his tenure in the MCU. This set specifically is modeled after the Mark XLIII armor, which was featured in 2015’s Avengers: Age of Ultron. An image of Thanos holding up the Infinity Gauntlet appears on the right-hand side of the box. I mean, it's a good looking titan-sized mech except for the diaper, plate between legs and some unfinished bits. But it just doesn't work as a model of the hulkbuster!

The finishing on the sides of the torso also leaves something to be desired, with gaps continuing underneath the shoulder joints. I like the golden bands around the sides though, which roughly correspond with the source material. The metallic gold details on the torso are correctly situated too, but become easily dislodged because they are each attached using one stud. Among various disproportionate areas, I think the Hulkbuster's midriff is the most apparent. The metallic gold accents on the chest and the belt-like structure around the waist should be directly adjoining, rather than separated. Removing this segment of the torso would greatly enhance the entire model, but doing so would entail significant modification and remove space for 76206 Iron Man Figure. Both arms narrow around the shoulder and elbow joints, which is disappointing after 71411 The Mighty Bowser demonstrated that similar joints can be disguised. The forearms and hands look superb though, including reinforced metallic gold armour. 242 drum-lacquered gold elements are provided in total, more than any other set. Placing the figure inside is fairly simple, as long as the legs are positioned shoulder width apart and the arms are posed by Iron Man's sides. This could be an unusual and appealing means of displaying the Hulkbuster with 76206 Iron Man Figure inside, but the surrounding structure looks unfinished. Once again, some mechanical details could have solved this issue.

There are no minifigures included in 76206 Iron Man Figure, because the entire set is just one large figure… — Price — This LEGO Marvel set depicts the Iron Man Armory (76216) building toy set. These Marvel toys are bursting with accurate details, features and classic minifigures to delight any fan of Marvel Studios’ Infinity Saga movies.

Where are the defenders from a few weeks ago who said just because some of the AFOL's don't like this set, we believe it shouldn't exist period? Again, the problem is SOMEHOW this set does exist, regardless of how we feel. They are a lot quieter now. The LEGO Group was founded in Billund, Denmark in 1932 by Ole Kirk Kristiansen, its name derived from the two Danish words LEg GOdt, which mean “Play Well”. Today, the LEGO Group remains a family-owned company headquartered in Billund. However, its products are now sold in more than 130 countries worldwide. Such detail is missing from between the Hulkbuster's legs, instead leaving two dark bluish grey plates exposed. These are easily visible if the model is displayed on a high shelf and could have been finished with continued texture. Thankfully, some mechanical detail is included behind the armoured knees, which also incorporate repulsors.

Reference

True, but you have to take into account that the development of a product roughly starts about two years before it hits stores, meaning toy companies are always working of conceptual art and early drafts of a script. During this development time, a lot can change to a movie or series, especially due to studio interference. That's how we wind up with LEGO sets of scenes that were ultimately cut from the movie or heavily altered.
