The strength of the first film was the bickering banter among the quartet of heroes, in the sequel it's relied on too much and is not nearly as well written; while still intermittently funny, the feeling is that it's trying too hard and the charm that smoothed over the previous film's rough edges is lost. The heroes as celebrities is an interesting angle, but not enough is done with it other than to give them opportunity to whine and complain, hardly an endearing quality and made worse when the stars point out how they have everything (and their wealth is clearly onscreen). This makes them less sympathetic and further erodes their charm. Only the Silver Surfer scores any kind of emotional reaction, which is surprising considering he is portrayed almost without emotion, but perhaps that's because he's given some subtlety. He's the only consistently interesting element and the mystery created by his arrival and then pathos of his situation is well done. His interaction with Alba's Sue Storm also good and reflects well on her, but otherwise he undermines the heroes we are meant to root for. The cosmic threat is never taken seriously and it's unclear why the audience should, it's another element that suffers from being undeveloped and ends up being as best inscrutable, at worst rather lame. The action is not very exciting, and the climax especially is not very rewarding on an emotional or story level, although it's brevity is perhaps merciful. Finally, the power-swapping is not only silly, but undercuts the 'powers are a curse' aspect that Marvel characters do so well. And, yes, once again any potential to do anything with it is not capitalised on, true to form it's used mainly for forced humour. Overall this is a film that is mostly unengaging and not nearly as fun as it thinks it is.
