Guardians Of The Galaxy (out Aug 7) is at its best when it’s trying to be funny. It makes great use of its 1960s/70s soundtrack and there are plenty of pop culture references. Not everything works through. The dramatic elements don’t resonate, the villains aren’t anything special and the script feels too “busy”. The public are going nuts for this film but I'd describe it as "good, not great." Grade: B.
