Finished the fifth part of Harry Potter and the Order of the Phoenix

The most challenging part of this book was actually keeping it in my hands and reading it. The reason is pretty simple: it's such a huge book with 800 pages, and after some time, my hands started to feel tired and uncomfortable. So, reading it wasn't always as comfortable as I would have liked. Still, I kept going and eventually finished it. It was also another new record for me, as I managed to finish such a big book.

Overall, it was, as usual, an interesting journey. One of the things I really enjoyed was noticing the differences between the book and the movie. There were quite a few of them, and it was interesting to see what was changed, removed, or added in the movie. All the main differences that I noticed are provided below.

• The portrait of Sirius Black's mother — In the book, the portrait is an important recurring part of Grimmauld Place, while the movie doesn't include it. 
• Regulus Black — The book explains that Sirius had a younger brother, Regulus, who became a Death Eater. Regulus is not mentioned in the movie.
• Percy and the Ministry — The book has much more of Percy's storyline and his conflict with the Weasley family. The movie removes most of this. 
• Harry, Ron and Hermione travelling to Hogwarts — In the book, Harry travels on the Hogwarts Express and Ginny introduces him to Luna. In the movie, Luna is encountered on the carriage to Hogwarts, together with Harry, Ron and Hermione. 
• Winky — Winky's drinking problem is a part of the book, but Winky is completely absent from the movie.
• The cold weather and gloves at Hogwarts — This is described in much more detail in the book, while the movie doesn't really include this detail.
• Quidditch — The entire Quidditch storyline is removed from the movie. In the book, Ron becomes Keeper, Harry/Fred/George are banned, and Ginny becomes Seeker. 
• Mr. Weasley's snake attack — The attack and its aftermath are much more developed in the book. The movie shows Harry's vision and the attack, but St Mungo's and much of the aftermath are removed. 
• Neville's parents / St Mungo's — Harry visits Neville's parents at St Mungo's in the book. This entire storyline is removed from the movie. 
• Sirius and Snape's conflict — Their arguments and Sirius's relationship with Snape are developed much more in the book than in the movie.
• Knight Bus trip — The book has Harry, Ron and Hermione travelling by the Knight Bus at one point; this particular trip is not shown in the movie.
• Harry and Cho's date — In the book, Harry actually goes on a date with Cho to Madam Puddifoot's teashop. The movie doesn't show the date; it only shows their kiss in the Room of Requirement. 
• Harry wanting to become an Auror — This is discussed in the book, but the movie leaves out this career discussion.
• O.W.L. exams — The book gives considerably more detail about the O.W.L. exams; the movie largely skips this.
• Harry and Hermione with Umbridge in the Forbidden Forest — The centaurs' role and the whole sequence are different/shortened in the movie.
• Harry trying to contact Sirius through the mirror — This is an important detail in the book, but the movie doesn't include Harry receiving/using the two-way mirror in this way.
• Umbridge's Educational Decrees — The book contains many individual decrees, while the movie visually shows them covering the walls and greatly simplifies this part. 
• Room of Requirement — In the book, Dobby tells Harry about the Room of Requirement. The movie changes how Harry discovers/uses it. 
• Harry visiting Mr. Weasley at St Mungo's — This whole hospital visit is removed from the movie.
