Sometimes, you can look at a trailer for a movie and think to yourself "Why are they doing this?" That pretty much sums up to reactions of most folks who took one look at the trailer for the new update of 1970's classic television show Charlie's Angels. Their was a revival of the series back in the early 2000s that was a huge box office success. The sequel wasn't as good as the original so there was never a third film made. Until now.
