I'm going to just start ignoring these kind of "underwhelmed" people when it comes to Disney...but let me rant a little first.
First of all, your rant was barely intelligible, but I did my best to get the gist of you being unimpressed with Fast Pass+ and the new additions.
At a high level, if you're not impressed with Disney, just don't go back. They certainly don't need more people jammed in the parks and especially the disgruntled complainers. I honestly can't completely blame you. They have dropped the ball lately.
That said, your basic premise of hating Fast Pass+ is that you don't want to plan. The reality is, you have to for the most popular rides but you really don't for most of the rides and most of the year. I've been multiple times and changed my times the day before with no problem. TSMM and 7DMT are among the most popular attractions, so it's not a shocker.
Do I wish they held out a few "walk up" fast passes so you could be guaranteed a fast pass if you choose to show up at 8am? Sure, but they are not going to manage 2 systems. I hate the new system too, but it can and does make your experience easier if you plan a little.
Unimpressed with the additions? I can't disagree that Toy Story Land seems to be underwhelming already, but let's give it a chance. Perhaps the TSMM expansion will be better than expected and the "kiddie coaster" may be more fun than Goofy's Sky School. Maybe not. I've argued for years that we haven't seen anything incredible since Everest and even that has no working Yeti today.
Bottom line is, Disney still has tons of classic attractions, shows, and even newer attractions to love. If you're going to let unfinished areas and a new fast pass system ruin it for you, don't let the door hit you on the way out.
