Yep, when they fixed a crash landed plane with duct tape, I suspended all remaining disbelief, and just enjoyed the characters. I suppose you could say I've moved on to a Lost happy place, and am no longer fixated on stuff that just didn't matter in the end.
Typically, I don't like sci-fi stories. I've never even seen Star Wars or Star Trek. Watching that stuff, for me, is like watching an unbelievable foreign film without subtitles. Yoda? Really.
Anyway, I figure the reason I loved Lost was because the writing and characters always felt real, even when the stories couldn't be explained logically. I could probably find a bazillion plot holes in something like Star Wars, but that wouldn't matter to the people who love those characters.
Once the duct tape came out, I gave up wanting answers for the unexplained. I realized that those things didn't really matter in the end.
