I'm sure it is fun to talk about living in a bunker, but for most of us it represents a lot of unnecessary expense and trouble.

Every security measure can be defeated. Bank vaults can be breached given enough skill, time, and proper tools. Security measures simply buy you time, and there is a way around every piece of protection you could come up with. As such, you should seriously consider how much security your situation really requires!
Furthermore, doors don't always go down as easily as the movies might make you believe. I've kicked a number of doors in my career... A couple of them went with a few good kicks from me (175lbs), whereas others stood up to our bigger guys (250lbs+) kicking on them for several minutes. The doors that took the greatest beating were often just solid wood doors that were well-built. For that matter, even breaching equipment doesn't guarantee success on the first strike!
There is always a weak link in the chain, and a determined burglar will exploit that link. A large number of burglaries occur through windows, too. The odds of a home invasion robbery are much more slim than the odds of a burglary, and you need to ask yourself why the criminal would be so interested in getting into your house when you are there (the vast majority of home invasions that I've personally investigated had some sort of drug involvement).
If you want some additional security, consider a steel outside security door, as someone previously mentioned in this thread. Those doors are actually relatively tough to defeat without breaching tools, as they simply can't be kicked, and can easily be keyed on both sides of the door. But, you have to ask yourself if you'd also want "burglar bars" on all of your windows as well (because a window becomes a weak link when the door is reinforced)! Still, a steel security door like this will certainly buy you a bit of extra time if you are home.
And, remember, EVERY security measure can be defeated! I've personally seen burglar bars and security doors ripped right out of the wall by a couple of burglars we dealt with around here a couple of years ago... They'd just hook a tow chain around the bars, then pull with their truck. In one instance they even ripped out half of the wall! Seems like more effort than it is worth, given the number of unsecured homes in the area, but it can and does happen in rare instances!
