The comparison to Splash are good...but, as you say, Splash is much better (much longer, more detail, more to look at, more story, etc.). 7D seems like a tentative project to me...like they weren't confident about it for some reason, and decided to minimize their risk by making it shorter and thus less expensive. Of course, they only have so much space to work with, but if they needed for space they could have found it.
