So here's yet another Harry Potter trailer and it looks like the Half-Blood Prince movie may actually follow the plot of the book. Maybe David Yates has run out of creative thinking or maybe he just realized that the reason people like the books is because the story is good and he shouldn't keep messing with it :-P . Anyway the trailer looks very promising and it shows a lot of Harry and Dumbledore on their excursions (which I would hope it would considering that's what mainly happened in the book, even though in the 3rd movie the Firebolt didn't even show up until the end and there was no winning the Quidditch Cup). Just their apparition alone is very cool looking. The trailer also gives a better introduction to Horace Slughorn for those people that are too lazy to read the books still. It also looks like the part where Ron eats the cupcakes filled with love potion will be hilarious. Harry-"Alright fine you're in love with her, have you ever actually met her?," Ron-"No.....could you introduce me?" Who wouldn't laugh at Ron being all crazy pants for some random girl that he doesn't even know? It also looks like they're actually going to have Ron get poisoned from drinking Slughorn's wine too. It's so impressive that Yates managed to use a whole scene from the book without changing it lol.
Anyways, I'm also really excited about getting to see the memories of Dumbledore meeting Riddle and the ministry man meeting Marvolo Gaunt (at least I hope this memory is in the movie). We also get to see some Quidditch action again and it looks like we'll actually get to see Ron doing a good job as the Keeper. Another interesting thing in the trailer are Luna's fun Specter Specs. They're really fun and glowy. We also see Hermione wearing something strange in the movie and she looks like she's about to cry so I'm not sure if that's Ron-Lavender drama or what's going on there. There's also sudo Harry and Ginny smooching in this trailer which I'm sure will make all the fan girls either happy or extremely jealous (even though it's of a fictional character *sigh*). The last things we see are Harry yelling at Snape (the Half-Blood Prince himself) and telling him to "fight back you coward" as well as a bridge being ripped to pieces (which I'm guessing is the one that Muggle Engineers would freaking out about in the book). This trailer looks like the movie is definitely going to be amazing. I'll just say it again, I'm proud of David Yates for leaving good things alone!
