It’s the most infamous address in TV history – 4616 Melrose Place – and this fall it’s finally back to the forefront of attention.

Given last year’s relative success of equally campy sister soap “90210,” it was only a matter of time before the nighttime soap that defined the 90s, “Melrose Place,” was brought back for one more dizzying spin of mystery, romance, backstabbing and blackmail.

Premiering tonight on the CW – that network with all the flashy teen dramas – “Melrose” is undoubtedly in the right home as all of the aforementioned key traits of the original return in a whirlwind of Hollywood glitter and grit.

And yet, the drama unfolds in an entirely different setting (although the Mexican brick courtyard remains the center): It’s a new decade, and basically everyone has either an iPhone or a BlackBerry. Technology has definitely made an upgrade since the original premiered way back in 1992. But besides that minor detail, the plot points seem to remain the same, as far as the adultery and scandal goes.

Because it’s Los Angeles, there’s both ends of the moral scale: there’s still the same biting bisexual blonde fashionista (“Supernatural’s” Katie Cassidy), the bad boy rebel (Shaun Sipos), the recovering alcoholic (Colin Egglesfield) and the mysterious new girl (Ashlee Simpson-Wentz, in her first role since “7th Heaven”). And then there’s the morally conflicted characters, like the cute couple who are forced to blackmail to make ends meet and the ambitious med student who turns to prostitution to pay off bills.

That’s L.A. for you. And it doesn’t help that an old character is killed off in the first act to know that this show may get intense.

On the other end of the TV spectrum comes the bright new comedy “Glee,” an entertaining yet dramatic attempt at explaining the phenomenon that is high school…with musical numbers.

It’s like “High School Musical,” but actually good, with some semblance of realism as far as teenagers actually behave.

Did I mention, with musical numbers? We’ve already seen the pilot, and with a promising teen cast that can sing too, “Glee” has a chance at making it through the year after its premiere Wednesda night on Fox.

It’s a classic story of the underdog, or in this case the underdog singing group: McKinley High Spanish teacher Will Schuester (Matthew Morrison) takes up the helm of leading Lima, Ohio’s lowly glee club after realizing its potential. The only thing stopping the team from being the best in the region is the evil doings of “Cheerio” head coach Sue Sylvester (Jane Lynch at her most sarcastic), and the mean-spirited Cheerios and football team.

But in reality, the musical numbers seem to be the only thing holding up the musical teen dramedy, which seems to be genre-jumping so much in one sitting that the caricature characters – the sensitive jock (Cory Monteith), the talented, gold-hearted singer (an amazing Lea Michele), the fashionable diva named Mercedes (Amber Riley), the crazy cheerleader coach – can’t hold it up.

But, the lines are funny and the script is smart, smarter than a lot of attempts at high school comedy these days (anyone remember NBC’s “Teachers”?). With Journey’s “Don’t Stop Believin” as its premiere song, “Glee” will probably take anyone with an open mind and a thing for toe-tapping in its grasp.
