For seven years Edgar Wright and Joe Cornish were working together on a script for Ant-Man than no doubt went through numerous drafts as the superhero landscape it was in shifted. Then, once the duo left (Cornish's departure with Wright further suggests it was a creative dispute) Anchorman mastermind Adam McKay, who was for a brief time in talks to direct, came on to do a massive revision. And then complete unknowns Gabriel Ferrari and Andrew Barrer made some even further redrafts. That's a total of five major writers providing input on the script, with no doubt further people adding suggestions. That may seem initially like a good idea, leading to a more rounded script, but in reality what this normally results in is an unfocused story that serves as a cinematic equivalent of a broth from a busy kitchen. If there's ever a real quality issue for the film, it'll probably stem from this conflict that exists on a fundamental level.
