At this year's Comic Con, I got the chance to catch the final free screening of Joe Cornish's Attack the Block. Ever since the film premiered at SXSW in March, Attack the Block has been touring around the country, with free screenings in pretty much all major cities in the US. There last stop was San Diego, as they presented the final screening of the film for a group of rabid Comic Con fans. The buzz for the film has been growing more and more with each passing screening and finally, after three months of free screenings, Screen Gems is releasing the film in limited release in eight cities across the country. Is it worth your money?
