This topic contains conversation that has likely been completely beaten to death already, but I'll post for the heck of it.
The Lost Ship in the Sky, was, in my opinion, one of the worst movies among the 14+1 movies DC has to its name. There was almost no mystery factor and the post-ending scene was less than satisfactory. I will admit that the "chase" (the part where Conan is tailed by pretty much every terrorist on that freaking ship and manages to freaking disable all of them) was a pretty decent scene, but that's about it.
The Raven Chaser was pretty good, but yes, it has flaws. The mystery introduced in the movie gave quite an ominous vibe and was quite fun to strike a blow at, but revealing a possible culprit, then switching to the "real culprit" just because of some thing about defiling stars or something (can't remember it) doesn't really make me happy. I also, like most people, actually wanted to see more BO influence throughout the movie BESIDES the two appearances of Gin (once at a house and once at that almost unforgettable helicopter scene, after all, more Gin makes better movie) because with just a few appearances, it didn't feel really like it should be sold around that little "battle with the Black Organization" feel.
But, overall, The Raven Chaser pretty much blows the Lost Ship in the Sky out of the water (or the sky, should I say? ) for so many reasons. That is my opinion.
