Well I wouldn't say boring. If you're not too fond of or don't much appreciate the sport, then of course it'd be boring. Any sport would be.

I hate the NBA, so any basketball game is boring as hell despite all the points scoring and action taking place. I love baseball so can watch it for hours on end despite it being a pretty slow-paced game interrupted by precious few seconds of excitement.

When you enjoy a sport, you can enjoy much more than just blatant action. You see more of what's going on, appreciate the intricacies of it all more, notice what everyone's doing and why, and see how it all ties in to the outcome of the game.

The majority of the world's population very much enjoys and appreciates soccer. So I'd hardly call it boring. I'd just call some people bored by it.
