Not much else to add to what other have already put so well, but I think it didn't feel "Orthodox" for the reason Shanghaiski pointed out: when people inquire into Orthodoxy, there are inevitably portions of almost every book that speak about the liturgy and what it's like, and it's always speaking about the St. John Chrysostom liturgy, so it's no surprise that things might've felt different than you expected.
I take issue with point/question #5 because there are not shades of Orthodoxy, there is nothing that is "more" Orthodox, or "less" Orthodox or "diet versus regular" Orthodox. It's either Orthodox or it's not. And that begs the question, What is Orthodoxy?
Orthodoxy is, most simply put, Apostolic Christianity. It is a pure confession of faith, an experiential reality and a visible ecclesiastical body, all of which are necessary to live fully in Christ.
It is not beards, pew-less naves, Byzantine chant, Byzantine architecture, Byzantine dress, so on and so forth. Those things, as wonderful as they are, are cultural expressions and embodiments of the Faith. And for the first 1100-1200 years of the Church's existence, there was a Western embodiment of the Faith that equally expressed and held the same Faith, ushered people into the same experiential reality of the life in Christ through His Body the Church. Only when the Western Church forsook the pure confession of faith and formally removed themselves from the visible ecclesiastical Body (and thus losing the true experiential reality) did she cease to be "Orthodox/Apostolic."
The Western Rite within the Orthodox Church, then, is the restoration of all that is salvageable from the Western tradition back into it's proper habitat of a pure confession of faith, experiential spiritual reality and reunion with the visible ecclesiastical, historical Body, which is now found in what we call the "Orthodox Church." Though really, it's simply the Apostolic Church, that has always existed and always held true to the pure faith and always lived within the experiential reality of Christ, etc.
So, while it might "feel" different, it shouldn't feel different, because it is the same confession of pure faith, it is the same reality that is being experienced and entered into through the liturgy and the Eucharist and it is connected to the same One and Only Holy Church of Christ.
