New Harry Potter movies suck for casual moviegoers?

I am a fan and have read all the books. but the sixth and fifth movies didnt always stick to the storyline, thats true but the seventh one was definitely amazing. If you paid attention in the sixth movie, you shoild know what a horcrux is. The horcruxes have HUGE importance in the defeat of voldemort and the sixth book explains all of this, also the seventh. As for Harry, Ron, and Hermione, they are great wizards because they have been doing this basically on their own while Voldemort has all of his followers and all of his own power. as for them not getting away from the snatchers, Harry didnt have his wand and that was a MAJOR setback to him. them getting caught is also essential to saving Luna, Ollivander, and Griphook, the Goblin. they need both Griphook and Ollivander to find more of the horcruxes so they are also very important.Not to mention Harry has defeated Voldemort, what? 5 or 6 times now, so he is worthy.
