I used to love watching indoor soccer because of this, my dad and I had season tickets to the Harrisburg Heat for years and years when I was younger. Highest scoring game I can remember was something like 42-2. Different scoring rules, but still the wall went in the net something like 20 times. Smaller field, its basically soccer in a hockey rink, with a half size (compared to outdoor soccer) goal on each end, and keep the hockey boards. I enjoy playing outdoor soccer, but agreed, not the most fun to watch.
