I will say this again, "This ride will be impressive." I'm going to use a comparison that I am not sure has been used here before.
Look at the attraction Dinosaur. It has had some changes from its inception but is largely the same attraction as the superior Indy attraction in DLR. From the queue to the attraction itself, it steals from the idea from a couple IP's that Disney doesn't own. It also is nestled in an area next to a parking lot carnival. Entering a museum and being privy to a new tech that enables us to study and bring back dinosaurs from the past is "meh" to many.
The attraction itself is not helped by its theatrical presentation, and it's current pre-show, dates the attraction in an unpleasant way. The journey inside the ride vehicle itself is jarring and it uses the darkness within to mask the underwhelming show effects. The final scene (climax, coup de grace, payoff...) can be thrilling or ho hum. I have to say that I really enjoy the photos where everyone is looking the wrong way...
Now let's look at INDY in DLR. It's had show updates and improvements in theatrical lighting, but the attraction is essentially the same as the day it opened. It had the benefit of being placed adjacent to some of the most epic and beloved attractions in Disneyland. The queue is still engaging and actually adds to the experience. The queue is it's own pre-show, full of scenes and interaction. You feel a part of one of Indiana Jones's adventures. You can even decipher the messages written in the "ancient" language.
The attraction itself is another story, one you are already familiar with because of the movies. Elements from the movies appear in the attraction and you get to experience those thrilling moments. The use of effects, lighting, and animatronics is part of "your" story and not just wow factor. The ride is something you can enjoy many times and is not overly jarring to ride. (Speaking of jarring, thank goodness they added cushioning to Matterhorn, because ouchie.)
So why did I write all of the above? I actually had a reason....what was it...?
Oh yeah....
We have all experienced Soarin'. It's a great attraction, even with it's Southwest Airlines, "cattle call", boarding queue (or boring queue). It is a shared adventure with 86 other people over California or now THE WORLD.... It isn't much to look at. Even in DCA, it's a hanger. The experience itself is just neat. Subtle motion combined with sound, smell, and a beautiful visual presentation. It is truly an immersive experience granted to you via your 5 senses. (6 if you see dead people.)
Now for "Flight of Passage". This attraction and it's attached sibling have been given a whole land. Your first experience with it will actually be before you enter the park. You will get glimpses of it for the first few years throughout the park. The themed combined show buildings will draw you in like a magnet. If you are looking for a comparison, look no further than "The Wizarding World". Much like the Indy experience, you will feel very much a part of a familiar space.
The attraction itself has a very leading pre-show queue, ala Indy and Splash. The visuals are engaging and may cause you not to fret over how long you've been standing in line. Once you reach the opportunity to board, you will only be among a few people. This is far different from Soarin". Getting ready to go will be exciting, not because of what you see, but because of the anticipation. Darkness around you will abruptly fade to reveal your actual surroundings. All of your senses will come alive much like Soarin', but this experience is more thrilling. You have actually become a part of this universe in a tangible way. Things that you have seen in the movie and movies to come, will be around you. You will actually know and feel what it is like to ride one of these amazing "beasts" through this fantastic world.
Comparing Soarin' to FoP, FoP is the Indy you've been waiting for.

As an aside, (which I offer often) the "boat ride" will be just as compelling.
