Hellew my lovelies!
Mostly if talk about sequel, it will be like Sembilu, Sembilu 2, Sembilu The Return then Sembilu Datang Lagi (Okay, saja suka hati buat title filem sendiri). But you get what I mean right? Tapi my sayangs, korang tahu tak this things doesn't apply to Marvel movies? Lepas Ironman bukan Ironman 2 then Ironman 3. Filem Captain America, Ironman dan Avengers ada kena mengena dan ada kesinambungannya. Sebab tu peminat Marvel ni akan gigih tunggu post credit dan after credit lepas setiap movie Marvel habis. If you want to have Marvel movie marathon so that you can understand the storyline better, here's how you watch Marvel Movies.
The Incredible Hulk (2008)
Ironman 2 (2010)
Captain America: First Avenger (2011)
The Avenger (2012)
Ironman 3 (2013)
Thor: The Dark World (2013)
Captain America: Winter Soldier (2014)
Guardians of the Galaxy (2014)
Avengers: Age of Ultron (2015)
Captain America: Civil War (2016)
Doctor Strange (2016)
Guardians of the Galaxy 2 (2017)
Thor: Ragnarok (2017)
Black Panther (2017)
Captain Marvel (2018)
Avengers: Infinity War Part I (2018)
Avengers: Infinity War Part II (2019)
Not only the movies, you should watch Marvel TV Series Agent of S.H.I.E.L.D Season 1 and 2 especially if you want to learn about Inhumans before you watch the movie. Another TV Series is Agent Carter. If you watch Captain America then you should know who Agent Carter is. It takes place after the event of war against the Redskull and Captain America was frozen (people thought that he's dead). If you watch the movies according to the timeline and the TV Series, you will understand the references mentioned.
I'm such a sucker for Superheroes movies. Ini baru Marvel, belum lagi DC Comics. If you follow the storyline like this, it will be more interesting. Not just some supehero fighting and actions for you to watch.
