This may be narrow minded, but Holmes in this series is annoying. I'm not sure why, but it just feels that way. However, the series still went on for several seasons. So I guess he still did a good job. But why does he have to jerk his face or shoulders every time he wants to emphasize something?
Elementary is surely not an action series. There's not even any decent side jokes in it. It's a drama. Every character is taking turns reading a book. So for those who like book clubs or book readings, this is the series for you. You will experience 100 percent dialogue, straight for 40 minutes per series. Yeah, like I said, it's like somebody's reading a book for you. Every week, for more than five seasons I believe.
And of course, there's no other plot. It's starts with a murder discovery. They get a theory. The theory gets cancelled cause they were wrong. And Mr Know-It-All finds a new theory that solves the crime. Same for every series, same for all the seasons, typically the same each time. If you look closely also, they'll slip in a name that will be hard to pronounce or spell.
So, you'll like it if you like it, you won't if you don't.
