You're confused. This will absolutely provide a full surround sound movie experience, as much as pretty much *any* speaker system in the hundreds or even thousands. The only place it will differ from those other speakers, costing two times, five times, ten times as much, is in subtle differences (though those subtle differences are not unimportant to many of us, especially but not only music junkies).
You keep talking about "feel." What you need to understand is that lower-frequency, tactile sounds (e.g. a dinosaur clomping along) are best produced by separate subwoofers. There are some boutique full-range speakers, costing tens of thousands of dollars, that effectively incorporate subwoofers, but that's actually a poor choice much of the time because subs are rarely best positioned at the same place speakers need to be located. For everyone else, and for every serious home or commercial theater out there, subs are separate from speakers that handle the midrange and treble.
So you are going to need a subwoofer. And there are no viable alternatives to the Pioneer speakers that will substitute for a subwoofer, or even come close to substituting. You can return them, and spend a thousand bucks on speakers, or five thousand bucks on speakers, but you'll still need a sub, and those speakers won't provide any more "feel" than the Pioneers.
As for the Pioneer sub, it's better than nothing. But for two hundred or so bucks, you can get a real entry-level sub from a company like BIC or NXG that should be decent in a smallish room. And for around five hundred you have solid entry-level options from good internet-direct companies like SVS, HSU, Rythmik, and Reaction that should be great in a smallish room, and able to hold their own in a medium sized one. For a big space or serious "feel," there are tons of options between five hundred and a thousand bucks. Of course, as with all things, you can spend more, too, but you don't need to to have a great home theater experience.
My two cents.
