Avengers was enjoyable, but so many plot holes and just puzzling decisions that I had to try really hard to stay in it.
Still, Vision. He was my favorite back in the day and he was great in Age of Ultron.
Definitely worth the money for the spectacle, but I'm hoping that the Marvel movies aren't fizzling over time. My hopes for the Infinity Gauntlet series are sky high. Nothing like that has ever been done in the history of cinema. Ever.
