Enjoyable new intro and version of the song.
I am a bit concerned about the series after that awful awful Donald birthday cake candle clip though. It's like they just pulled the most overused generic bit of "comedy" from a 100 year old barrel and slapped Donald in there.
In fact it seems to me that ever since the classic shorts Disney have really struggled to find the right tone for Donald in animated form. His shorts in House of Mouse were also pretty crappy for the most part. The comics are just soo much better it's almost scary.
Preach! Post classic era, they've often seemed to take his speech as an excuse not to even try giving him a fuller personality, leading to several cases where Don's little more than a slapstick magnet with no backbone whatsoever; downright blasphemous considering his well known anger. The House of Mouse shorts you bring up are a good example, it's clear the staff was much more interested in doing Mickey and Goofy shorts than Don's (so you have stuff like an episode centered in Scrooge McDuck where both Mick and Goofy interact more with him than his freaking nephew). Quack Pack, too, reduced him to a prop most of the time, albeit that series in general rarely had quality writing so no surprise.
In the positive side, I think the original Ducktales series handled him well more often than not (sacrilege of removing his main role from Barks' comics aside) and the newest Mickey shorts are finally starting to tap some of Don's potential with pretty fun characterization and dialogue.
I'm hoping that this new series makes the effort to take full advantage of Donald. Portraying him as an overprotective parent of the nephews could go either way, but I'm intrigued about his past with Scrooge being the first season's arc, and thrilled that he's portrayed as a veteran, if retired, adventurer.
Love that Webby fangirls over him too; please, let that be justified for the most part.
One more thing. For the love of God, don't make him the load, the scaredy fellow who sets the group back. Some clips have pointed in this direction and I'd loathe if they made him the guy that sucks the fun out of the room, it should be the opposite. For all his virtues and achievements, I feel Don Rosa, who's certainly enjoyed tons of popularity with modern Duck fans, didn't help the cause by making Donald so subservient and slapstick-prone in several of his stories. Not to say he didn't give the Duck some awesome moments, but in many tales he wrote him as a comic relief and little else, where in Barks' Scrooge adventures Don was an important asset and actively (and often
eagerly) contributed to the goal at hand.
