That's pretty much my impression of Wells - he's caused all of the problems he's trying to get Lois and Clark to solve, without his interference Tempus wouldn't be a problem, none of them would have ever travelled in time, and Utopia would be a lot safer than it is, if it ever existed outside Wells' imagination.
The only way that Lois and Clark being able to have children can work is common ancestry at some point in the comparatively recent past, no earlier than say Neanderthal man, and probably a good deal more recent than that. I made it a 150,000 years ago in my Superman Returns crossover, but even that is pushing it.
