I usually find those people complaining about TMP being "the most boringest" are usually like Plinkett says - aged around thirteen with the attention spans of mosquitoes...Most thinking adults really like it.
Nope, sorry. I was an adult when it premiered - which in fact may have been one reason I was underwhelmed by it.
That is, assuming that your intent was to so characterize adults who find the movie boring - your attempted mockery of those people by using the phrase "the most boringest" is a failed parody which renders your intent there somewhat muddled.
"Most thinking adults," BTW, have never sat through this or any Trek movie - period. So even if you could offer some evidence that you represent "most thinking Trek fans" in some sense superior to those who dislike the film - and you can't - your observation fails as a simplistic and thoughtless overgeneralization.
