River Song is the best companion on Doctor Who

(Thanks! Don’t worry about taking a while, I have the same problem.)A note on spoilers: If anyone reading my arguments for this debate has yet to finish the 6th series, then that person should stop reading now. I’ll give spoiler warnings for anything from the 7th series onwards, but using markers for earlier events is too complicated.My points:1. River is the Doctor’s equal.“This was addressed in my first point, but I'll say it again: Rose is made to be relatable to the viewer. River is amazing, don't get me wrong, but she is not relatable. She is alien to the viewer, and at first sight is extremely unrelatable to us. That is her first flaw as a character.” River is not so much unrelatable at first sight as she is mysterious. Her first episode is mainly focused on the action, rather than on her. However, River becomes more relatable as time goes on, something I’ll elaborate on when rebutting my opponent’s second point. In any case, having a very relatable character isn’t necessarily good. Jack Harkness, for example, is adored by viewers because of his futuristic attitude towards sex and his inability to die. Being a unique character is often better than being a generalized one. Rose is an average girl living an average life; unremarkable in all respects other than her status as the Doctor’s companion. River, however, is fascinatingly strange, and the mystery surrounding her is appealing to viewers.2. Rose is possessive.“I will concede that Rose is possessive, but note that she does grow up in Journey's End and The Stolen Earth. With the Doctor still around (and before what happens later in Journey's End) she isn't visibly jealous of any of the companions.”On the contrary, it’s during The Stolen Earth that she is envious of the other members of the Sub-Wave Network, and in her final scene, insists that the meta-crisis Doctor isn’t enough. [1]3. Her tangled up timeline is realistic.“I touch on this on part of my second point, but I concede the untouched remainder of your statement.”I have nothing more to add, and close this point.4. She has catchphrases“If you see the phrase "Bad Wolf" you are reminded of Rose Tyler. That is her signature, and it is written across time itself. River's catchphrases are brilliant, but nothing can compare to Bad Wolf and Rose.”I concede that “Bad Wolf” holds deep ties to Rose Tyler, however, I’d like to note that these ties are not revealed until halfway through her tenure on the show, and that the words themselves are not telling of Rose’s personality, unlike River’s catchphrases.My opponent’s points:1. Rose is made to be relatable to new viewers.“Rose is a normal person working a low wage job. She has a mom and a boyfriend. She is a completely normal person, and that is attractive to new viewers. She has no idea of the universe around her and, like the Average Joe, probably could care less. She is swept up into the doctor's world in the blink of an eye and, like anyone, would be confused. She is us. She needs explanations, and that is part of what makes her attractive to the viewer.” In the same way that Rose is attractive to new viewers, River is attractive to experienced viewers. By the time of River’s introduction, people watching should ideally know an extensive amount about the show. This is mirrored in River’s knowledge of time and space, and the viewer can identify with her as well as her advantage over the Doctor. In addition, by season four, the Doctor Who audience is well used to the “new companion routine.” Character meets the Doctor, is surprised he’s an alien, exclaims that the TARDIS is bigger on the inside, and pinches themselves when they reopen the TARDIS doors. This becomes repetitive and somewhat dull, until River breaks the mold entirely.2. Rose's life is less obvious."Right off the bat, the episode after we meet her, River dies. Her story ends, just like that, before it really begins. We know the signs of when she will die, as she brought them up, and we know when we will see her last. That kills any tension around her or the 11th doctor when action ramps up, as we know nothing fatal will happen to them until it is her time.” “Time can be rewritten." And it has been on Doctor Who, many times. There is never a guarantee that a character will die at a particular moment. Rory was erased from history in Cold Blood and was later brought back into existence in The Big Bang. The same thing occurred the following season, only this time, the Doctor was thought to have died in The Impossible Astronaut, and was discovered to have faked it at the end of the series. [2] Not only that, but there are plenty of other plot twists and tense moments in River Song’s storyline, such as when she throws herself out of a building hoping for the TARDIS [3], or when her parentage is revealed. [4] River is anything but obvious.Sources:[1] http://tardis.wikia.com...(TV_story)[2] http://tardis.wikia.com...(TV_story)[3] http://tardis.wikia.com...(TV_story)[4] http://tardis.wikia.com...(TV_story)
