Very much so. I lost it after the 2nd Avengers and basically had to power through just due to wanting to finish the Infinity Saga. Granted, it took me about a year after End Game was out to watch everything. I haven't really watched any of the new ones.
I feel like they are average. The ones after the streaming service shows I never followed and maybe I just don't think it's healthy just to watch the entire series in full because it is all connected and there are continuity problems. Thanos dying means resources are finite and that's never solved.
I wouldn't say I am tired of it so much, as I still enjoy them when I do take the time to watch them. I have always been inconsistent with how often I watch them and which films appeal to me. There are a few which are out which I am wanting to watch but just haven't gotten around to yet.
