I have been looking at the Friends - at season 2

been looking is imperfect past tense, so if you use ' to be + a verb' , the verb has to be in present tense (i.e looking , playing , buying etc. ) When you use 'Friends' in a sentence, referring to the series then you don't have to use 'the'.

I like Friends so much ,this is the best Comedy. Actually ,in China have a same there is a similar television drama called 爱情公寓, and this is my favorite television drama .you know ,The Vampire Diaries, you know, is my favoritew too.I am waiting for the season four,( I've heard just like 2012 ,The October broadcast .isn't it. )

The bit in () doesn't make sense. I hope this has help you ^^ If you don't understand, please tell me :)
