No, it definitely gets better. What I'd say about The Wire is that it's definitely something that should be considered as a whole rather than just season by season (even though everyone, myself included, is going to have his/her favourite season). The overarching plots, the character development, the resolutions you get throughout the show, the amount of detail and care for every single aspect of the story, is unrivalled in any other show for me, and it's once you have the full picture and see the range and the depth of the show as a whole that you can truly appreciate the genius of it.
A lot of people find it 'boring' at first, it's a slow burner. It doesn't necessarily get faster, but it engages you in a way no other show does and it becomes addictive because of that. I'd definitely recommend to at least get through season 2 which you may not enjoy that much on first viewing (it's a recurring thing among The Wire viewers) and to push through season 3. If by episode 4-5-6 of season 3 you're still not that convinced, maybe you could give up. But I very strongly doubt you will.
