Wesley Crusher

Ensign Wesley Crusher is a recurring character in Star Trek franchise, mainly in the TV series Star Trek: The Next Generation and the movie Star Trek: Nemesis.

Why He Sucks

 * 1) He's a complete Creator's Pet character who aware of how hated he is, but stays on the show anyway, to the point where he's one of the most well-known examples and the former trope namer. Then there's the 1987 Writer's Strike.
 * 2) He loves to meddle in just anything the characters are doing.
 * 3) He can be considered a Gary Stu - and a self-insert for the creator of Star Trek and The Next Generation, Gene Roddenberry, whose own middle name was Wesley - since he solves virtually every major problem or crisis there is, and is praised by everybody for what he does even when he doesn't deserve to be praised.
 * 4) Speaking of which, some of the crises happened because of him, and he still get praised for it! Case in point, in TNG's second episode he accidentally disables the ship's engines (albeit while under the influence of a virus that makes people drunk) while it's right next to a star that's about to explode, then at the end of the episode everyone falls over themselves to praise him because he had the idea of asking Data to solve the problem that he created.
 * 5) Anytime he does something wrong for the characters, he doesn't get punished for it.
 * 6) His story arc has a somewhat confusing and unsatisfactory conclusion, with him somehow gaining godlike powers and then going to live on a planet populated by Native Americans. He then appears again years later in the movie Star Trek: Nemesis, but is barely even seen on-screen and doesn't get a single line of dialogue.
 * 7) Misleading last name: His last name “Crusher”, implies that he can “crush” others or things, but doesn’t live up to that name and is actually a spoiled annoying brat.

Redeeming Qualities

 * 1) Like the rest of TNG, he starts to get a lot better starting in season 3, being shown as actually capable of making mistakes, and on the occasions that he does save the Enterprise he's shown working with a more experienced crewmember (usually Geordi or Data), making it seem a lot more plausible.
 * 2) He's only a main character for the show's first three-and-a-half seasons, after which he only has a small handful of guest appearances, one of which is in a legitimately great episode where he's faced with the choice of whether or not to own up to accidentally causing the death of a fellow cadet.
