I wouldn't say he's "so" hollow. His hollowness isn't that much more than what we've seen lately over the past year since Generations Skyfire. At least they figured out ways of folding panels around Magnus to cover up some of the gaps. The chest gap is deliberate to fit Minimus Ambus. The lower leg gaps were necessitated due to how the feed fold up into the legs in alt mode, shame that the feet themselves appear hollow underneath. Other than that, it's a pretty good offering in the classics scale. Looking forward to having this one in my collection.
