TSS was great back in the day when all the people mentioned by glytch were still there. I watched it religiously. I even met Patrick and Leo when they did an autograph session at a local CompUSA.
In my opinion it started going down hill when the co-hosts (like Kevin, Sarah, etc.) started hosting the show when Leo and Patrick went on their many vacations or whatever the hell they were always off doing. It became a show ran by kids when they hosted. Then when Leo and Pat left for good, I lost interest and watched very little TechTV until the last couple months.
I enjoyed Martin Sargent's show (I forgot what it was called though...), and Kevin and Sarah's show, Attack of the Show. However, I doubt i'll be watching too much more of that because Kevin Rose just left. Friday's episode was Kevin's last episode. He is leaving G4 to start his own web based show.
There is actually a lot of shows on right now that have great potential if it wasn't for the horribly obvious scripting. The thing I miss most about TSS was how it felt so "real." I never felt like they were reading off a screen, it always seemed like they knew what they were talking about. But today, shows like Attack of the Show and X-Play are absolutly horrible because they are so obviously scripted; the people even admit it, and make comments about it! It's ridiculous!
One show i've always hated is X-play. I hate Adam Sessler, and have even grown to hate Morgan Webb, who ruined her image with bitchy attitude and gothic attire. I loved her on TSS, but she's been corrupted by the hell people call X-Play. "Brutally honest" game reviews (as they call it) is one thing, but they step over the line. Tommy Tallarico on Judgement Day does a great job of giving "brutally honest" game reviews to bad games. Adam Sessler, on the other hand, is just stupid about it. It's tough to take him, and Morgan Webb at times, seriously when they act like immature retards.
There are, however, SOME good things about G4TV. Some shows I really enjoy include Icons, Judgement Day, and though horribly scripted, Attack of the show. I love learning the history of great games, software, hardware, and developers on Icons, even if the show is a complete rip off of VH1's "I Love the 80s" series. On Judgement Day, Tommy Tallarico and Victor Lucas in my opinion give the best video game reviews around right now. They're funny, always have a fair amount of pros and cons for the games, and always find the interesting and appealing points of the game to share.
I think that show Arena is a great idea but, that host has got to go. I always thought it would be cool if video gaming was considered a sport, but I think they approached it the wrong way. I'm not exactly sure how, but I do believe there is a way to make the show work, and be very enjoyable to watch. I'll have to give it some thought.
Anyway...
thats my $0.02
