If you somehow missed the Harry Potter boat and wanted to read all the books now, you'd have to flip through 4109 pages spread across seven books. Or if you just want to catch up with the Harry Potter movies instead, you'd have to sit and stare for 19 hours and 38 minutes for all eight movies. Or you could just read this comic.
Sure, it's a pretty huge comic but I'm sure you could get it done in five minutes. Remember: Harry Potter, good. Voldemort, bad.
