MARVEL studios is sure on fire. The x-men titles should be worth watching.
the X-Men movies are not being made by the same film studio as the other Marvel superhero movies
the X-Men Sequels and the Wolverine movies are being made by Fox (cuz they own all the "mutant" characters) Fantastic Four re-boot and Silver Surfer movie (if they ever get made) might also still be Fox
Spider Man and Ghost Rider are made by Sony
Previous Punisher Movies were Lionsgate, Daredevil and Electra were Fox but now any future Punisher/Daredevil/Electra movies will be financed by Disney and take place in the same "Cinimatic Universe" as The Avengers
i believe the 1st Hulk movie was a different studio than the 2nd one
and also i think the 1st Ironman was a different studio than the 2nd one
the Marvel Superheros have been made into so many movies coming out so fast because they've been made by different studios that were competing with each other
DC Superhero movies are all being made by WarnerBrothers because Time-Warner has owned DC for a really Long time, Disney has only owned Marvel for a few years
also
Disney bought LucasFilm so that they could buy Industrial Light & Magic so that the up-coming Disney-made superhero films would have better special-effects than the up-coming superhero movies that are not being made by Disney
