ELI5: War of Currents; Did Edison screwed up Tesla?

I just watched "The Prestige" today, and so I was wondering why Edison is up on Tesla's ass? (It's just a little thing in the movie I was curious about).

What happen if we use Tesla's AC methos now days? Would it be more efficient?

Like you're 5? Edison was making money providing power on a proven idea (DC). Tesla came along with a new, better idea (AC) and Edison knew it was better. Since he couldn't beat it, he decided to be really mean to Tesla. Edison went around to big crowds and said things like, "AC IS REALLY DANGEROUS WATCH THIS"* and then would electrocute large animals.

*Paraphrased.

Tesla responded by running AC through his body to power light bulbs so people could see it was safer. Pretty cool. Basically Edison was threatened by Tesla's cool ideas which were better than Edison's. Edison was a mean guy. Tesla died broke and alone. :<
