Boring if Juve win again this season? I dont think so, boring or not is not depend on which team win the title but more about the whole competition. It will only be boring if Juventus always win while other competitors such as Roma, Milan, Napoli etc always lose points when they may get the points easily.
Yes it's totally depend on which team win the title. If the competition is really tough, then the point gap between each other surely will be short and there will be always different team on top position in every week. But Juventus have got the first position since 5th gameweek and no team can snatch it from them until now.
Othe thing is that 7points is not that big for such competition, still many matches to be played.
7 points gap is pretty huge, which in other big leagues have shorter gap (Premier League 1 point, Spain 4 points, Germany & France 3 points). Also, until end of half season, there is no big opponent Juve will face except Roma. Lets say Juventus lose to Roma, and they still ahead by 4 points.
