Avengers: Age Of Ultron might still be lagging behind unlikely leader Furious Seven in the 2015 box office stakes and will fall into third spot behind Jurassic World any day now, but Marvel wont be too concerned. The sophomore outing for Earths Mightiest Heroes is closing in on $1.4 billion worldwide and, with Ant-Man just a few weeks away, Hollywoods most bankable outfit is already guaranteed an eighth-straight year of enviable profitability. Yet its fair to say the acclaim for Age Of Ultron, while significant, wasnt overwhelming or universal. Much as director Joss Whedon did his best to give everyone their share of the spotlight, the films plot struggled under the weight of its unwieldy cast of characters and the villain himself was somewhat sidelined by the necessity of setting up strands for future MCU adventures. And then there were the jokes. As youd expect from Whedon, there were plenty of belly laughs to act as a counterpoint to the high-stakes drama and heady action too many for some. Theres no question Marvel tends to skew more towards the brighter end of the colour spectrum than their DC counterparts, sometimes to the chagrin of moviegoers whove had their feathers ruffled and hackles raised by a joke or two too far. Nevertheless, even the studios most ardent critics would surely acknowledge that its films yank on heartstrings almost as often as they tickle ribs. In the course of 11 films there have been tear-jerking moments aplenty, so heres a rundown of the 20 saddest moments in the MCU (so far).
