The movie HAS to be good based on what we know. All of us could write a decent script.
I think 10 Gambit fans would write 10 different scripts with different feeling and type of movie.
Gambit is a really comlex character so sometimes it is hard to make him fun, serious, mysterious, charming, dark and self-loathing at the same time.
That is why fans has different opinions about Asmus` Gambit.
Some fans really love it and think that it was perfect. Some like me think that it was good but not good enough. And some really hate it because it wasn`t Gambit that they were expecting.
I think the same situatuon will be with movie. One fans would say I want him to be with Rogue, others would say I want pop-corn movie about thief and third group of fans would love to see Mutant Masscare drama.
Deadpool was a great mix of humour, drama and action with some erotic. Gambit movie need to be the same great mix of different things.
