It's a little disappointing because things happen even if you try to stop it. For example, with Savannah, MC's mom asks if she should bring her in for an interview at her. Even if you say she shouldn't, it happens anyway as if you said yes. Of course, the Astrid is another one. For Astrid, I could understand because it never really indicated that you could stop it. But it did make it seem like you can stop Savannah from going to MC's mom's company.
Some choices seem to matter (mostly for unlocking scenes between the mom and Jamal). But all the other choices don't seem to make a difference, so it feels pointless to even have those choices. I'd say only have choices that will actually affect the story and get rid of the choices that really don't impact the story at all.
