Matthew McConaughey and Christian Bale team up with DRAGONS to make a movie and it barely breaks even. What happened?

I think (and I believe i am relatively alone in this) that Reign of Fire is actually a pretty good film despite McConaughey's best efforts to make it not good. However; a lot of this stems from the fact that I don't believe that Matt McConaughey is a very good actor.

the plot is that dragons have destroyed the world and only a few people left on the planet know how to defeat them. This is a dumb premise but can be relatively entertaining if you simply suspend what it is you know about satellite targeting missile systems and instead believe that a well-placed axe in the hands of a good-looking person is far more effective.

I, for one, really hate movies that suggest all the world's military were defeated by {insert whatever creature here} but yet some one person is capable of winning based on knowledge that ONLY he (or she) has but for whatever reason this person has not shared this information with other people about how to use melee weapons against something the size of a 7-11.

anyway, I am being too mean to it: This movie is actually quite entertaining if you can just look past the stuff that I said above and pay a bunch of attention to Christian Bale (good actor) and less attention to the star of this movie Matthew McConaughey (not a good actor outside of Dallas Buyers' Club.)

This movie has magnificent production value and is definitely worth watching. I actually regret that I did not see this in a theater.

I love this trailer because of the typical voiceover

This movie isn't great, but mostly this is because of redneck-sounding Matthew and probably a weak script. The special effects are fantastic so if you like that sort of thing you might really enjoy this one. This film was nominated for and actually won one, of the awards for best visual effects.
I don't know, maybe it is just me but i think that Matthew McConaughey is actually what ruined this movie.
