Why She Is A Smart Scientist

 * 1)  As mentioned above, despite being the second-youngest member in the Loud House, she is extremely intelligent and creates a lot of interesting inventions.
 * 2) She is very helpful with the rest of the Loud family when they need her.
 * 3) Although some of her experiments had gone wrong, she is one of the most mature Loud sisters.
 * 4) Lisa also likes to realize experiments with her siblings. Not only her siblings, but she also likes to realize them with people outside of her family.
 * 5) She also has a fun side too, as seen in "Party Down" where she goes hype over chocolate, although it might be taken too far at one point.
 * 6) She has a cute design as well.
 * 7) Her voice acting by Lara Mill Miller is great.
 * 8) She cares about her family and friends.

Bad Qualities

 * 1) Despite her intelligence, she can be boring or act like an idiot in some episodes, like "Snow Bored", "Making the Grade", "House of Lies", "School of Shock" etc.
 * 2) Lexi Janicek was not a great voice actress for her in live-action appearances.
 * 3) She can be a bit of a know-it-all at times.
 * 4) She is sometimes unlikable, such as in "Friend or Faux" and "Making the Grade".
 * 5) Depending on your view, she has been getting too much episodes in Season 5, though not so much like Lincoln and his gang and him himself. Lisa episodes also are: "Blinded by Science", "School of Shock", "Friday Night Fights", "Dream a Lily Dream" and "The Loudly Bones".
