Take series 9 for example. The arc of 'the hybrid' sounded increasingly interesting throughout and we were hinted at the possibility of seeing a proper gallifrey story and a possible half dalek half timelord during the course of the series. Then when the final episode came, it was basically an epilogue to face the raven rather than a story in it's own right and 'the hybrid' pretty much came to nothing of any significance, meaning that for me, the previous good work in making the arc seem interesting was a complete waste.
Whether you agree with me on that particular example is neither here or there. My basic point is that big arc/small arc/intrusive/ made to seem standalone, however it's done, what matters for me, more than anything else about an arc is the pay off and if the finale is underwhelming, and the arc has hyped the finale more than it deserves, than the effort put into the arc, however much or little effort was put in, was all a complete waste anyway.”
Agreed entirely with this.

I've had different stances in regards to the arcs over the past ten years of the show. As examples go, I found Bad Wolf in Series 1 to be compelling - it didn't distract my enjoyment from the individual stories, was satisfying in small ways when I was fed the illusion that I'd 'spotted' a grander scheme in play later on, and above all (this is where it gets subjected to individual tastes) the finale delivered a satisfying conclusion to it. In retrospect it didn't force-feed the arc down your throat as you went along so there wasn't heightened expectation. And it eventually delivered a decent finale, a rewarding pay-off.
Skip ahead a few years, and we have the Series 5 arc. Far from being subtle it signposted itself absolutely everywhere it could. That build up was mostly okay even if the antidote to subtlety. Cracks in the wall in The Beast Below and Victory of the Daleks were nice little nods to something greater - admittedly it's mostly tacked on hype, but in the moment you enjoy it. And ultimately the finale would more or less pay off as well as one of the better ones in the past decade. The build up though was jarring for me, with the Weeping Angels completely undermined by the threat of the crack in the Byzantium, and then later Rory's death feeling formulaic and tacked on as a result of that same arc. It went to show that the build-up of the arc was every bit as important as its resolution.
Series 6 would prove just one year later what happens when it all goes wrong, and the arc becomes the main event. The show wanted to have its cake and eat it all at once, chuck us in the deep end with a compelling and potentially show-shifting storyline, whilst maintaining the monster-of-the-week status quo it had always had. It was a choppy, bumpy ride filled with annoying hype references along the way ("the only water in the forest is the river",
The Doctor's Wife) and Day of the Moon undermined the format of the entire show itself by asking whether it was best to explore the mystery of the little spacesuit girl, or have "some adventures". It immediately drew a divide between the two, putting the arc on a pedestal and them worst of all it fundamentally failed to deliver a satisfying conclusion too - resulting in an uneven series with some superb standalone stories but an arc that got it wrong on so many levels (for me at least).
Series 9, as has already been said, struck a very good balance again. It didn't feel repetitive like we were going through the arc-motions, nor did it feel like it had become all-consuming. The hybrid arc was intriguing in the same way Bad Wolf was - signposted but not obnoxiously so for the most part. The finale comes along and as episodes go it did a lot right - as a Clara fan I felt I should have enjoyed it, but all the same I didn't. Why? Because the episode dropped the ball in terms of the satisfying build up it had had up to that point. The arc that had been teased went next to nowhere in favour of a plot point that had hit its tragic but dramatic high in the previous two episodes. All these teases of Gallifrey, revelations about the Hybrid, much less subtle but nonetheless interesting build up to where Ashildr's character could be headed - all these little elements came together for sure (and in many ways I feel this was the same with Series 4 - another arc that burnt out too early, as
Journey's End managed to feel dull for much of its runtime compared to what came before) but they ultimately played second fiddle to something else, and unecessarily so.
All in all it's about balance. As Tom Tit has said, the mainstream audience seems to respond rather well to the format of the show - which doesn't need changing if it isn't broken (Moffat treads a fair few fine lines in this regard - but in retrospect I appreciate that he keeps the show feeling rather fresh most of the time as a result). I do think though that the show needs another finale that really delivers a sold resolution to its build up again. Series 9 came so close to getting it right - if it had done so it would possibly have been the strongest series for me - but it stumbled with perhaps one too many two-parters that made the whole thing a little clunky and ultimately a finale that focused on the wrong plotlines (again, said as a Clara fan) and didn't live up to the hype, expectations and possibly even the promise of what had come before.
