There's a lot, and I mean a LOT, of differences between the Netflix series and the films.
There's someone on Tumblr, avannak, who gets into the finer details of this frequently.
I think what's going to be the most striking bit are the differences in Hiccup's movie self VS his series self. His movie self is more.....He went from the soft quiet child to being the one who wanted to stand up to everything- but he's never really been a jerk about it. Even when it came to Drago, he wanted to work peacefully, and knew when he had to man up and fight like a viking. His series self however...... seems to get a kick out of pushing and shoving his way to the top; the Thawfest episode is a good example. He utilizes his intelligence in ways that are not befitting of his character. He was badly bullied in the movies, but never sought to take it out on anyone, whereas we see in thawfest that he practically leaps at the chance to throw snotlout off his high horse, so-to-speak.
How you react to his 3rd movie self is really going to come down to how much of the series you view as being canon.
I view all of the series as being mostly canon, though I give some leeway for things like the fact that dagur and heather aren't mentioned in the second movie, or other general plot holes. I think the show portrays hiccup's transition between the two movies pretty well, aside from the fact that I'd rather see some more well-thought-out plans from him (but I think its just due to the writers). hiccup has that internalized viking culture and doesn't hesitate to put snotlout in his place or use a combination of intelligence and physical prowess to surpass others. and it's not like he has anything to prove by doing that- he's already the dragon whisperer and heir to the hooligan tribe. I think it gives hiccup too much credit to say that him being a jerk sometimes is out of character. he can be pretty immature on occasion, but that's not out of the normal- all the vikings are pretty immature sometimes, as part of their culture. he can also be pretty mature, and he's gained much more maturity throughout the series and second movie than he had in the first. his experience with leading his group of friends during rtte makes him into the more mature (but still capable of being immature) person he is in the second movie, who's able to handle unexpectedly losing their father and being responsible for their entire tribe.
I'd actually seen the second movie before I ever watched rtte, and even before seeing the series I was disappointed in the characterization. not hiccup's, but the rest of the gang. it felt as if hiccup and astrid had gained 5 years in experiences and the others hadn't. I haven't found anything online to confirm or deny this, but I really hope there is another 5-year time skip for the third movie (though I doubt there will be). I'm more interested in seeing hiccup's actions once he's comfortable in his role as chief than when he's learning how to lead the hooligans, because he's already had so many learning-leadership experiences- that's practically been the whole series thus far. I'll accept whatever they end up doing, though, because it isn't following the books anyway so nobody can really say where it should go.
