I really enjoyed the Iron Man films, the Thor films were OK, Guardians of the Galaxy was really good, but all of the Avengers films leave me cold. However, after having made the effort to see the first couple, I felt I had to complete the circle by watching them all to see how it all wrapped up, jeesh that's a few hours I'll never get back. All of the actors do a really good job. The actual characters they're playing are interesting and the humorous interaction between the characters is great. As others have said, the actual story itself is just too contrived and the feeling of "let's just jam everything we can into this thing to try and make it work, irrespective of whether it truly hangs together" really shone through for me, I started to give up near the end because it was just too ridiculous. For me it is a case of lots of flash, bang, wallop, bright and shiny colours and no-one will be bothered about the story. If you like this sort of thing, then go for it, but just totally failed for me and the 4 out of 10 it got was for the characters and their humorous interactions - like the Thor and Quill 'man-off chat' about who is in charge, funny, but if that is nearly my high point, which it nearly is, then that is a real indictment of the rest of the film.
