I tried watching the weekly PPVs, while better than any modern wrestling really only the early Jerry Lynn/AJ/ Low Ki x-division matches hold up.
But even the worst shitter, like random puerto rican guys they brought in because they were jacked don't do obvious cooperation like you see in all modern matches. Throw better punches too.
That said all the 2005 PPVs were great. Now that you know TNA was always going to be hopeless it's a lot more fun to revisit. Can't wait to see what 2006 brings :)
