I'm going to say that the booing had nothing to do with the skiing in the film as the Montreal crowd was going ape shit over big lines and cheering for good shit the whole weekend. That film was premiered at the wrong time as it was the film right before 4bi9. Sweetgrass' Signatures was one of the sickest ski films I've ever watched but when it premiered at IF3, I just couldn't get into it. It's hard to get a crowd that's completely riled up from watching the sickest, most progressive shit in skiing to watching a great story. I'm sure Invinciblea has some merit as a ski film and I look forward to rewatching it and giving it an accurate portrayal.
That being said, booing is something that's going to happen and while it's unfortunate, disrespectful, and rude, without crowd reaction premiering movies wouldn't be fun. I think back to last season at the UVM premiere of Refresh when the whole crowd was chanting "Warren" over and over during Warren Miller's great narration. Sort of a shame that they missed the narration but here I am a year later recalling it because it was different.
4bi9's movie was awesome. Invincibles should have been the last movie in the block, then a 5 minute break and begin the next block of films with Gunnie Season.
Live and learn. Thankfully winter is right around the corner and we can get back to skiing.
