Explaining what facts? If you are so confident about what you believe then could you explain why theatrical sequels weren't made for the following films after favorable foreign and worldwide grosses? Just in case you haven't done your research like I have sequels were planned for all of these films. Also, Batman Begins and The Incredible Hulk(2008) are not sequels because the movies have nothing to do with the storylines of Hulk/Batman and Robin.
Lost in space Budget(80mil) worldwide gross(136mil)
Van Helsing Budget(160mil) worldwide gross(300mil)
League of Extraordinary Gentlemen Budget(78mil) worldwide gross(179mil)
Godzilla Budget(130mil) worldwide gross(379mil)
Constantine Budget(100mil) worldwide gross(230mil)
Elektra Budget(43mil) worldwide gross(56mil)
Daredevil Budget(78mil) worldwide gross(179mil)
The Hulk Budget(137mil) worldwide gross(245)
Batman and Robin(125mil) worldwide gross(238mil)
Men in black 2 budget(140mil) worldwide gross(441mil)
Spawn Budget(40mil) worldwide gross(87mil)
Star Ship Troopers Budget(105mil) worldwide gross(121mil)
Jurassic Park 3 Budget(93mil) worldwide gross(368mil)
The Punisher Budget(33mil) worldwide gross(54mil)
Starship Troopers had a sequel that went directly to video so it doesn't count.
There's a big difference between turning a profit and making enough profit that a studio is willing to take on the financial risk of a sequel. Sequels are almost always more expensive and certainly aren't guaranteed to see an increase in box office over the preceding film, so if a film only has marginal profits it doesn't really make sense to greenlight a sequel in most circumstances.
As I stated earlier in the thread, observation of which films get fast tracked sequels reveals that a return of about 2.4 or 2.5X production budget is the line which pretty much guarantees a quick sequel. The lower a film falls below that level of return the dicier its chances of a sequel become.
Let's have a look at your list:
Lost in Space, Van Helsing, Elektra, Hulk, Batman & Robin, Spawn, Starship Troopers, and The Punisher all grossed less than 2X their production budgets putting them into the category where a theatrical sequel is not to be expected under most circumstances. A Punisher sequel may happen (although it's being delayed and delayed and delayed) because the budget level is so low that a sequel doesn't carry much risk when the DVD sales of the first film are taken into account.
LXG, Daredevil, and Constantine all grossed around 2.3X their production budgets, just below that slam dunk sequel level, but solid moneymakers nonetheless. LXG and Daredevil likely would have had sequels had it not been for their main stars (Connery went into retirement and Affleck wavered on a sequel and then went through a career dip). Constantine 2 is still being kicked back and forth and is likely dependent on the studio and Keanu Reeves striking a financial deal that they can both live with.
Jurassic Park III had a great return on investment (although not as spectacular as that of the two Spielberg-directed JP films) and Jurassic Park IV is in development.
Men in Black II also grossed much more than its production budget, and usually we would've seen another sequel, but here the situation was complicated by the fact that Will Smith, Tommy Lee Jones, and Barry Sonnenfeld had such incredibly rich participation deals that the studio ended up seeing realtively little profit. Hence, no Men in Black III.
Godzilla actually had a good return because of the strength of its foreign box office, but I guess the studio felt it was one of those films that lots of people saw but few really liked and a sequel was likely to do substantially worse.
