This episode is absolutely perfect! To create a strong series opener, especially for Doctor Who, it's essential to include several key elements, such as introducing the companion, their first meeting with the Doctor, and the entry into the TARDIS. This episode accomplishes all of these aspects remarkably well. After watching it twice, I can confidently say that I didn't notice any major flaws until some more dedicated fans pointed them out. The issues mentioned were only minor and wouldn't disrupt the viewing experience. Overall, this episode strikes an ideal balance of mystery, comedy, and action, making it enjoyable for casual viewers.
