I just saw the 2 movies last night and I will share what I think of the movie in this article, I will not include any specific spoolers (unless other wise noted) but I will provide a general overview of the movie and my thoughts of the movie.
Hulk Vs. Thor
This movie showed what the hulk really is, pure unrelenting power. With no one or thing to hold him back he is unforgiving and one of the most powerful superheroes in the Marvel world. This movie showed what the hulk can do to an entire world and to a god with his power unfiltered and also what Bruce Banner has sacrificed to keep the beast under control. It was a great introduction to Thor and his world, it showed the kind of heroes both Thor and Bruce Banner/Hulk really are.
Hulk Vs. Wolverine
This movie showed the hulk more as the superhero but still with the power and rage we have come to know and love. It shows a bit about weapon X and the pain wolverine went through but also showed his love for what he does best. Hulk vs. wolverine is an epic battle that as usual neither asked for but with neither backing down. With a couple little surprises and with Deadpool not disappointing from the previews I think this is the better of the two movies because of the different battles and more variety of characters/bad guys.
Hulk Vs. (minor spoilers)
These movies where done very well, the animation was great and the dialog was spot on. It was done similar to X-Men: Evolution, with the way the characters were drawn and color was done. These movies were about Thor and Wolverine as much if not more about the Hulk. They explained more about the histories of Thor and Wolverine then Hulk, with Hulk they showed more of his power and rage at the beginning of the movies than his back story. In a way the movies were an introduction to Thor and to show people what he is about and to show what wolverine is really about, compared to the live action movies. One more thing I would like to say is Deadpool was a very nice addition to the movie and the expression on Sabertooth in one of the scene toward the end of the movie was priceless. I think it would have been nice if the movies could have been at least an hour long a piece, combined it was somewhere around an hour and 20 minutes. You can tell they cut them down and left out some of the back stories and battle scenes. Over all the stories were great and I will watch it again and again.
Hulk Vs. Future release previews (minor spoilers)
