Eternals was not so long ago.
And DS2 and L&T had really bad reception and legs, they were carried to decent totals by inertia but still dealt a lot of damage. So that makes 4/6 of the most recent movies heading into gotg a drag rather than a boost.
Now that gotg is good, only 4 of the last 7 are bad, or 3 of the last 5. People will probably view marvels, cap, bolts blade etc as open questions which could easily go either way, and that will drag on their openings— though if any individual ones do turn out good, it will show up with better legs. And if they all turn out good, probably we will mostly have goodwil restored… except for Kang/multiverse stuff, which is the central pillar of the saga 😬
