It's an exciting time of the year for TV fans. Hopefully your favorite shows got renewed (you can check here to find out), but there is also a freshman class of new shows to speculate about, complete with trailers to whet your appetites for the fall TV season.

Collider has weeded through the nearly 30 sneak peeks offered up this week at the New York Upfront presentation to bring you what we think look like the five best shows of the upcoming season. Up next, we'll bring you the five worst, but in the meantime you can catch up with more upfront coverage with the fall schedules for CBS, ABC, Fox, NBC, and The CW as well.

Star Trek: Discovery, CBS All Access

Getting this series on its streaming service has been an uphill battle for CBS, but it's going to be worth the wait (at least, that's the feeling the trailer inspires). Set 10 years prior to the original Star Trek series, this new sci-fi show stars Walking Dead alum Sonequa Martin-Green as a human raised by Vulcans who is made captain of the USS Discovery. It looks pretty great, and with CBS All Access being on a no-holds-barred streaming service (as opposed to a broadcast network) is definitely a point in its favor.

The Mayor, ABC

The setup with this comedy is that a rapper (Brandon Micheal Hall) runs for mayor of his small California town -- and wins. He has no experience, but he does know that things need to change. Much like ABC's Black-ish, this comedy looks like it has boatloads of potential to be both hilarious and have a timely point of view. Yvette Nicole Brown, Lea Michele and David Spade star alongside Hall.

The Crossing, ABC

Set in present day Washington state, The Crossing chronicles a small town, led by the local sheriff (Steve Zahn), that is suddenly playing host to nearly 50 refugees (with hundreds more washing up dead on the shores) from an unnamed war-torn country. The real kicker: it's a war from 150 years in the future, so there's obviously a mystery/sci-fi element at play here. Part time-travel show, part character drama, it comes from the minds of Jay Beattie and Dan Dworkin, who have worked on such previous dramas as Surface, The Event and Revenge, and boasts an excellent cast.

This one is a big gamble for ABC -- and might be a huge swing and a miss -- but the trailer makes us think The Crossing could be a winner, with potential to be the big new breakout mystery show of the 2017-18 season. And like any good sci-fi show, it can touch on real events happening worldwide right now, examined through a science fiction lens.

Black Lightning, The CW

The CW has shown it can do superhero shows very well, plus Black Lightning looks like it skews more toward Jessica Jones / Luke Cage in terms of the storylines and tone. If that is the case, that is a potent combination indeed. Cress Williams is an excellent leading man choice and it boasts Greg Berlanti (Arrow, The Flash) as an executive producer, which bodes well.

Splitting Up Together, ABC

It was tough choosing the last spot on the list for best trailers, but we're going out on a limb with this comedy because Jenna Fischer is outstanding in the trailer, Oliver Hudson looks like he may be a good match for her, and ABC has a stellar track record when it comes to family comedies.

The only drawback is that we wonder where a show like this goes a couple seasons into its run, but that's a worry for down the line. In the here and now, Splitting Up Together looks like a solid addition to the Modern Family-Goldbergs-Middle-Black-ish cadre of shows.

Honorable Mention

The Gifted (FOX), Law & Order True Crime: The Menendez Murders (NBC), Life Sentence (The CW), Me, Myself and I (CBS), The Orville (FOX) and Young Sheldon (CBS).

All of the honorable mentions have some serious potential to be great, and offered up some solid trailers that at least make us curious to check out the pilots.
