I'm assuming this is about your Tekken review, but by the looks of it, it wasn't the score that's the problem; the problem was that your review didn't really say anything useful, particularly about TTT2 and the movie. You didn't talk about what the movie was about or who it followed. You didn't mention what new features were in Tekken Tag 2 Prologue. You didn't mention what four characters were available in that demo. Etc.
GameSpot gave it pretty much the same score you did, but their review was way better since it mentioned a lot of useful information. They mentioned TTT's gameplay still holds well, but it has some graphical issues and the lack of online is disappointing considering that other fighters that got rereleased had online included. They mentioned what four characters are in the TTT2 demo, and that there are new tag tricks.
However, the demo lacks the characters' move list which is a big problem (for me at least) since I only use two of those characters; I need to look at the move list for the other two to learn their combos and moves, but without a move list, I won't know how to properly play with them which will take away a lot of my enjoyment. I also need to constantly look at Xiaoyu's move list since she's more complex than most of the Tekken characters. Lastly, they talk about the movie's plot and what characters is mostly follows, which sounds terrible. Once I finished reading their review, I said that it was not worth it.
But you, instead, complain about the characters and having 'insert coin' on the screen (which has always been like that since the first game). The characters have always been silly and crazy since the beginning of the Tekken series, but that's one of the beauties of the series. It has a great, crazy diverse cast of fighters, and most of them feel entirely unique in terms of fighting style. Also, some of the characters like Kuma, Panda, and Roger (the kangaroo) aren't meant to be taken seriously; they're just for comedic relief. It's evident that they aren't meant to taken seriously once you've seen some of their endings; they're silly but funny. Lastly, you got the price tag wrong; it's $40, not $50.
And oh yeah, everyone knows Eddy and Christie are for the noobs. Many newcomers love them because you can just button smash with them.
