I really don't understand the hate. It wasn't a "stupid" movie, for the most part, and even if the plot was predictable, it was A LOT of fun to watch. Never trust the Tomato Meter, anyway. Rotten Tomatoes is notorious for falsely summarizing reviews as "good" or "bad".
ROTTEN TOMATOES ***LIED*** by misrepresenting mixed reviews! 76% of critics don't even think Anchorman 2 is barely ok, most of them think it's horrible! WORST MOVIE I'VE EVER SEEN, DON'T WASTE YOUR TIME, YOU WILL BE BORED AND *EMBARRASSED*!!!
