Wasn't there like 6 different writers that touched the script for Homecoming?
I'm kind of neutral on the writers, but while I think Watts did a decent job (and I think he did great in pulling off the Toomes car scene, even most scenes with just 2 people talking like May and Peter or Peter and tony were done well) I don't really necessarily feel like he added enough to the equation to feel like I need him back to see what he can do for Spider-Man. I would even go as far as saying I wish they gave someone else a chance.
If for no other reason, the fight scenes were good, but they lacked a certain bombastic quality that have characterized all Spider-Man films, even the poor films. There was a real low-key sense to Spider-Man in his fights, and even his webswinging, that even getting someone else who can breathe a little more life into that area would be greatly appreciated. That's not even saying what Watts did was bad and I even think it may have been part of Sony/Marvel's mandate to make things as different as possible from the previous films by possibly wanting him to downplay aspects like webswinging, but I think even if you look at how the Russos directed Cap in TWS, his powerset is pretty low-key and grounded, but they did a great job at making you feel the impact of the fighting and there was a great sense of actions scenes that felt dynamic, even when they mostly amounted to lots of shield hits and throws.
Besides, if Sony is potentially screwing up the rest of the universe with these spin-offs, I want the very best Spider-Man we can possibly get under Marvel in the MCU while we can, and I feel that Watts just comes up a bit short. I know there will still be years of Spider-Man we can get with Holland, so maybe Watts deserves at least one more chance, but hey maybe Spider-Man having a different director every time is another approach they can have as well so we get different takes. Just keep the same writers, similar to what they've done with Captain America. Then eventually they may stumble on a winning director/writer combo like the Russos and Markus and McFeely that can carry the Spider-Man franchise wherever it needs to go. As much as I enjoyed The First Avenger, imagine if they were too scared to give the Russos a chance and stuck with Joe Johnston. We may have never gotten The Winter Soldier in the film that we got. I personally think they made the right call and I like Johnston as a director.
