Star Wars Episode VII and Avengers 2 are my big two for 2015. Abrams' Trek films were fun movies with script problems and I'm pretty sure that Arndt will write a much better script than anything that Orci/Kurtzman has shit out. At least it can't be as bad as the prequels! Right? RIGHT? Plus the 10 year old SW fanboy in me is going fucking crazy thinking about the fact that there's going to be an episode 7. The first Avengers was pretty much exactly what I wanted out of the film but I'm also a slightly biased Whedon fan - since Whedon is still in the picture, I'm in day 1 for A2 (plus Ultron, fuck yes).
Superman/Bats - I'll see it but MoS was just okay and Goyer

. I'm definitely curious as to how they approach this though, could be good if they do it right.
Avatar 2 - On one hand, I'm in no rush to see a sequel to Avatar but on the other hand when Cameron makes a sequel, it's fucking fantastic (T2 and Aliens). We'll see.
Finding Nemo 2 - I always see (non-Cars) Pixar, Nemo is good but not something that needed a sequel. It'll still probably be worth a watch though so I'm there.
Bond 24 - Skyfall rocked, Mendes is returning, I'm fucking there.
JP4, DH6, PotC5 - Previous entries soured me on the franchises, not really getting hyped for any of these yet.
lol Smurfs 3
Don't forget about Ant-Man! It's Edgar Wright, it's going to be gold.
