My personal thoughts on the shows that are in discussion:
Two and a Half men = Got old after the first season. Same jokes over and over and i'm happy its almost over.
Big Bang: Also, same nerdy jokes over and over, got boring and is rarely funny anymore.
How i met your mother: Started off GREAT, fell a little short and then really picked up hard for season 4. The current season sucks balls though and is not worth watching anymore. (I'd like to point out that NOTHING HAPPENS anymore, which is the sad part. Before there were all these twists with relationships but now its all focused on the married couple and ted is hardly a minor character)
True Blood: (Keeping in mind that i've only seen season 1, and i've heard season 2 is better) The show was entertaining but the season ended horribly. The "big reveal" was a horrible twist and the villain was someone you hardly know throughout the series. Resulting in a "oh..its HIM? ... lame" ending. Still i will watch season 2 eventually though.
One of the main problems with the 3 sitcoms first listed is that not much really happens anymore. Its like the same characters lives doing the same things over and over. One of the things i really liked about the earlier episodes of how i met your mother were that there was the whole ted/robin relationship and then ted and stella? (was that her name..the girl from scrubs). Either way, now its just kinda bleh, nothing HAPPENS and not in a seinfeld kinda way. At least in seinfeld the "nothing" that happened was different every time.
SHOWS TO WATCH:
Weeds: Starts off alright but REALLY gets crazy in the 2nd season. Everything just keeps escalating its actually QUITE good.
Breaking Bad: Jimp reccomends this, i have them on my computer but have yet to watch
The Office and 30 Rock: Seen and love both of these shows, probably my 2 favorite of all time. Absolute hilarity ESPECIALLY the office.
Anyways, thats my TV post. I've watched like all these shows over the last year on my computer during classes at school ;)
