I would have thought that Buck Rogers would have developed in a better fashion than what we see in both the series and in this Annual issue.
Buck Rogers has a long history as a comic and as a franchise. So why do we see a very limited development of this well known character? In this Annual Buck Rogers is finding himself, or better put, he is comings to terms with his time travel by learning about his past love. This is a closure issue that may allow for a better development of future issues. I do not know that this closure needed a whole annual issue.
