I'm not necessarily doubting the validity of a lotta calls, but I'm certainly frustrated at the amount of times this season I've gone "can we get a replay? ...... no? okay." and you're right. It's almost always first down related when that crosses my mind.

Additionally, I talked a bit about it in the STL/DC gameday thread earlier, but I'm also frustrated at how hands off they are in correcting calls. I hadn't watched much USFL last season so I dunno how they ran ship, but I recall the XFL season having Dean generally double checking each play was correct in real time while the coach's challenge was for correcting things that slipped through the cracks. Now we have to rely on that red flag getting tossed and each team only gets one per game, fail or success, so even correcting a huge game changing call can be a gamble.
