So in conclusion and much reflection again:
What is my view on Enterprise?
Star Trek Enterprise (The entire series) is an official Star Trek prequel that is more than likely a First Contact and Temporal Cold War Time Line.
1. The event of First Contact is confirmed to exist within Enterprise's time line in the episode "Regeneration".
2. The Xindi Attack was brought about by the Sphere Builders who were apart of the Temporal Cold War.
3. Both the events of First Contact and the Xindi Attack continue to exist within the events we seen within Enterprise's time line.
4. Also, the studio has confirmed that all Star Trek TV episodes and films are canon. So the events we seen on Enterprise suggest that things are not in the Original Prime Time Line, but in an Altered Time Line.
What is my view on Enterprise as a Star Trek series?
1. Star Trek Enterprise has the weakest cast.
2. Star Trek Enterprise has some of the worst performances.
3. Star Trek Enterprise has the worst believable setting or things within it's universe.
4. Star Trek Enterprise has a knack for not explaining things that are important.
5. Star Trek Enterprise does have a lot of entertaining episodes. However, you have to turn your brain off sometimes to enjoy them, though.
6. Star Trek Enterprise has helped explained a few mysteries within the Star Trek universe.
7. Star Trek Enterprise gives you the impression that it has a different history than the one that was described to us in the other Trek series.
Is my viewpoint more fanon than canon?
Well, fanon is defined as...
fanon is used to refer to "fan canon" (of which the term is a portmanteau). It applies to certain "facts" that may have been accepted as a truth by a large number of fans, and thus either replaces an established canonical fact in the minds of those fans, or fills a plot-hole.
Well, there is a lack of a proper explanation on part of the TV series itself or the studio on whether or not Enterprise is an Altered Time Line or a part of the Prime Time Line; So this forces Trek fans to come to their own conclusion on what "Star Trek: Enterprise" really was. So no matter which way the fan decides to interpret Enterprise, his interpretation is going to be viewed as fanon and not canon, I suppose.
