5. Van Helsing (2004)

Bear with me, because I haven't gone crazy, and I'm not saying that the plot of
Van Helsing was any good (it wasn't: it was horrible and confusing and unnecessarily convoluted). But the concept - Dr. Van Helsing goes around facing off against a variety of supernatural baddies - is balls to the walls awesome. Imagine if, instead of being rendered in the CGI-heavy, "We're all doing this for the cash" way that it was so apparently rendered, it was far more seriously-aligned, in the vein of something like
The League of Extraordinary Gentleman. The fact that what we actually got - an endless array of badly animated set-pieces - hasn't stopped me from catching a glimpse of this movie from time to time and thinking, "Hey, this could've been really cool, if it hadn't been directed by Stephen Sommers." In fact, whilst writing this, I've actually realised that what I really want is for somebody to just remake that Godawful
League of Extraordinary Gentleman movie, 'cause that's basically what this was anyway, right? Yeah, that's what we want: something good that is like either one of these properties, please.
