I think it suits the situation we are in. Question mark for me comes when there are situations where teams sit back in front of us (this isn't a new problem btw, so not of Dyche's making), and I think that's probably only solved in the transfer market. If we stay up this season, that's an issue (one of a few) I'd hope is addressed in the summer.
What I think suits us from the point of view of culture is a fast-paced, direct style. That doesn't need to mean "long ball", but whilst we warmed to them as people at times, the likes of Martinez and Lampard tried to implement styles which don't really suit the nature of our support.
What we've seen from Dyche has been fairly effective and has largely got the crowd onside, but it'd need to be adapted a little next season if we don't want to end up in the lower reaches again IMO (again, not really his problem, more of a personnel one)
