I kinda liked Danny, he was a different kind of Who character, and I don’t see him as a stick in the mud, he was a counterpoint to the Doctor, someone who offered Clara stability, roots, a family in contrast to the Doctor who, let’s be honest, just offers danger, adventure and the ultimate sightseeing tour (and despite what some fans say I’d still contest that the majority of people would only be able to do that for a finite period before feeling the need to settle down.) I think they could have handled the character better, and I would have liked to see him travel in the Tardis, but overall I liked Anderson as an actor.
Despite my complaints, I actually thought Anderson and the character were fine. I just don't think they work in Doctor Who.
Part of that wasn't the character's fault but how the show tried to shoehorn in a conflict with the Doctor. First we had the mysterious "anti-soldier" stuff in the Dalek story. Obviously that was trying to set the ground work for when the Doctor meets Danny. But, it just didn't feel right. And, then the conflict with Danny. It just didn't feel right that the Doctor would be so darn mean for no good reason.
For the character himself, well, I've called him a stick-in-the-mud. Maybe he had good reasons to live a quiet life at home. And, all of that could make him interesting in a different show. But, for me, Doctor Who is all about embracing the magical adventure of traveling with the Doctor. Obviously, DW is different things to different people. But, for me, the show is at its best with that context.
Danny was diametrically oppossed to that. That explains a lot of what I didn't like about him. Now, if he had been a one shot character, not such a big deal. But, he really influenced the regulars and was a recurring problem. And, in the same vein, I didn't like the part-time companion role of Clara. Again, embrace the magic of travelling with the Doctor! It felt like Danny was the anchor that kept dragging Clara back.
I do agree that in the real world, anyone would want stability after awhile. I guess Danny represents the real world reaction to lots of "adventure" like that. Of course, Danny was fighting a war but I'm sure the companions would experience similar trauma. However, for me at least, Doctor Who isn't about that. Or at least not to drag you through that for a prolonged period! Again, if he were a one shot character making that point, that's just fine. Of course, YMMV for what Doctor Who is about.
I do see the point that Moffat was making with the character and the role he wanted Danny to play. I think through a combination of weak writing to set that role up and the fact that the character doesn't work in DW context is what made him feel like a stick-in-the-mud bore. And, the effects on the other characters that were required to artificially keep that tension going (PE teacher?!) just didn't work or suit the regulars.
