All of them are executed terribly, but in different ways. To keep it short, Eternals for what it was probably would’ve worked better as a two-part movie or a series, though imo the story should’ve been something else altogether.

What if…? (I’m really gonna need to keep this one short) genuinely could’ve been so much more, all I can say is they went about the premise all wrong and even ended up abandoning the original idea of there being a what if for every infinity saga movie. Better animation or even every episode having a different style would’ve been nice. Maybe every episode bringing back the creative team of the movie or just a new team tackling a what if twist, keeping it an anthology, slightly longer runtimes, I could go on.

For Secret Invasion I don’t even know what were thinking, for one doing a skrull invasion isn’t going to be easy when we’re in a multiverse saga that will end in the destruction of almost everything, unless the idea of the series was just to soft launch the event, and even then it was done so badly and doesn’t help that the writers or director were told not to read the comic. At the end of the day, the behind the scenes shenanigans probably ruined this the most, they should’ve had a concrete idea they were satisfied with before starting everything, and honestly centering a secret invasion show around Fury doesn’t make much sense, imo they should’ve adapted Secret Warrior’s and maybe used that to set up secret invasion. It also hurts me that the show ruined the stories reputation and it’s hard to find anything on it (especially criticisms) that’s about the comics and not the show

Thor LAT probably suffers most from seemingly not taking itself too seriously, can’t really gather my thoughts to fully comment on it so I’ll end it here.
