I can now see why his role is an issue for you but in all honestly that is your fault, not the average viewer. They'll remember his love for Thor and how Loki mind effed him.
I've seen Thor once, I've seen The Avengers twice, I have an above-average long-term memory, and I sporadically discuss these movies on forums, so I probably remember more plot details than the median viewer.
If the movie doesn't work for people who have not seen an MCU movie before never mind all the relevant MCU movies multiple times, then the movie doesn't work in my opinion. There are plenty of sequels out there that can be appreciated by someone who didn't see the original.
