For someone who is not a fan of the movie/franchise, and has a clear predisposed opinion on them, he spends too much time posting in the relevant threads. Same goes for you. Your posts reek wishful thinking, rather than well formatted opinions. So yeah, people don't take you seriously, they're just irritated by your (constant) bs.
Now, to give you some perspective, I am not a fan of F&F and never cared about it. Go and see how many posts I have in the relevant threads, or if I watch these movies in midnight premieres.
