What characteristics does Becks have, and what are similar beers? I haven't been drinking for years. And over the last month, I've been trying a small variety of beers, but they all had a taste I can't put my finger on that I didn't like. I was starting to wonder if I had lost my taste for beer. However, I was lucky enough to have had a Becks the other day, because I remembered it was a beer I used to enjoy. Anyways, I really liked the Becks, so I'd like to know what I'm drinking and why I like it. Also what are other similar beers to Becks?
Beck's is a pale German pilsner brewed by Beck's Brewery headquartered in Bremen.  The actual beer you drank was likely brewed in St. Louis, however, as Beck's is wholly owned by AB InBev.

Pale Lagers as a style are usually straw colored, up to a light gold with a white head.  The flavor is very light and dry with only slight malty sweetness.  A little crisp hop bitterness without too much hop aroma.

Most "macrobrews" will be somewhat similar, though the stock "American" variant of Pale Lager like Budweiser or Miller will have a corn sugar flavor to them and likely be a bit lighter in body.  Beck's claimed to adhere to the German Beer Purity Law which would prohibit the use of an adjunct like corn.

St. Pauli Girl is a very similar beer, and I think is even brewed in the same town as the original Beck's.

If you want to stick with imports just about any pale German lager is going to do it for you since it's a very traditional style.  Anything by Spaten, Hacker-Pschorr, or Weihenstephan is solid and usually pretty easy to get ahold of.  Pilsner-Urquell is also a great beer, but it's in the Pilsner style so while it's still a pale lager Pilsners can have a sulfur-y or buttery tinge due to the green bottles and slight diacetyl.  Pilsners also have a strong hop character and bitterness.

If you wanted to try local or American brewed versions just about anyone's Session Lager (Full Sail comes to mind, as does Notch if you're near MA at all) should be similar.  According to this list on BeerAdvocate you should be near Berghoff and Baderbrau which will both make traditional German styles.  Some breweries, Baderbrau included, will call their pale lager a "Lawnmower beer".

Branching out, Sam Adams Boston Lager is a style called Vienna Lager which may also appeal you.  Though it will be significantly maltier than Beck's.  Anything with Dortmunder in the name will also be similar, though hoppier but not like an American Pale Ale or IPA or anything.  You might also be interested in any brewery's Cream Ale, which is an Ale version of the Pale Lager style.  Kolsch style beers may also appeal to you since they share the same light body and slight maltiness.  Kolsch's are hybrid beers which are fermented warm like an Ale would be, but then cold conditioned like a Lager.  Officially Kolsch can only be brewed in Cologne, Germany, but many American breweries will make a Kolsch style since it drinks really well in the summer and provides more flavor variety than pale lager or Cream Ale.

Does that help?
