You can't criticize this movie
To anybody that says you can't criticize The Smurfs because it's aimed at children, you are everything that is wrong with modern movie making, I've seen a few topics and posts within topics that use this excuse to defend this trash and quite frankly it's the single most feeble, absent minded excuse you can use, it's the exact same excuse people use to defend movies like Transformers saying "It's a popcorn flick what did you expect?", just because a movie is aimed at children doesn't mean it's exempt from all negative feed back, if that were the case we wouldn't have amazing children's movies that can also be enjoyed by adults, like The Lion King, Toy Story, A Nightmare Before Christmas and Home Alone, if they were all free from criticism then they wouldn't have put the time and effort into them to make them the classics they have become, they would just be a barage of lame jokes, forgettable characters and a sign at the end saying "Hey at least the pretty colours kept your kids amused for an hour!".
All movies must be held to the same standard of quality otherwise we get The Smurfs, the epitome of laziness, bad CGI, bad jokes, plots that start then either lead nowhere or just disappear altogether and actors that genuinely look like they know what they're doing is an abomination to cinema.
Sure this may make a quick buck now, and this quick buck may warrant a sequel, but I will bet my life that this movie will have absolutely no impact on anyone.
