I watched Solomon Kane on-demand last night. *sigh* I really had a hard time divorcing myself from the source material. Because of that, honestly, I spent most of the movie saying "WTF?" Maybe if you've never read the original Robert E. Howard stories, you'd enjoy it more than I did.
Like Conan the Barbarian (1982), in and of itself it is a passable adventure movie, but the Kane has no more relation to the literary Solomon Kane than Conan did to Howard's Conan.
Even on its own, though, there were things going on that didn't make much sense or were disappointing.
Here be spoilers, ye have beene warned.
