As far as movies go, most of what Crackle offers are titles that are likely on rotation on basic cable networks. This means you have a good chance of finding something worth watching, but you're not going to find anything terribly new. Still, the selection is worth browsing, as it does cover quite a few genres. Also, it's worth noting that movies are only available for a specific period of time, with about five months being the average.
Sifting through Crackle's content is fairly simple, as you can sort videos by most popular, featured, or recently added. Otherwise, you can browse through genres, like Comedy, Crime, Drama, and Anime. As easy as it is to navigate, though, I do have a couple of issues with the interface. For one, there is no search function, which means there's no easy way to look for a specific title, actor, or director. Second, clicking on, say, a movie title to get more information brings up a brand-new page instead of a lightbox-style overlay. This can get annoying because you have to then press back to return to the list of movies you were browsing through. What's even more annoying is that this step back returns you to the top of the movie list, which means you have to scroll all the way back down to where you were previously.
The Watchlist is a useful feature for keeping track of programs you want to watch. There's even a page with recommended Watchlists that you can add, either piecemeal or as a whole, to your own queue. While these lists aren't exactly filled to the brim with Best Picture nominees, it is nice that there is some curated content for you to sift through.
