Is a Canon 18-200mm lens a good idea?

Currently I have a T7, and I don’t like the non-versatility of the kit 18-55mm lens, i.e. I need more focal range. Is a Canon 18-200mm lens a good option for a replacement. I’ve seen a lot of reviews mostly positive about it, but I still would like some advice, I understand telephoto lens’ tend to have mediocre sharpness. If not suggestions are greatly appreciated.
