I agree on the criticisms of the match, and find the number of people that use the word "fight" to refer to guys taking turns allowing the other guy to hit them bizarre, but you're way off base saying there was no heat. That was easily the hottest NOAH crowd in recent memory, they were eating the shit up.
I think Suzuki has very consciously allowed his opponents to work their kind of match when possible in this run, which is probably the right thing for an invader champion to do. The problem for me is that Marufuji and Sugiura's respective match styles are pretty shitty. It's telling that I enjoyed his matches vs. Taniguchi and Takayama, far more limited guys where Suzuki had to do most of the heavy lifting, far more than the Marufuji and Sugiura matches.
That said, I think the way he worked the Marufuji and Sugiura matches could be seen as a point in his favor, even if it actually resulted in worse matches for my taste than if he'd just taken control and slotted them into a Suzuki Match. You have to consider what the goal of this run is and the audience he's playing for.
