I don't think now is the best time to judge. There are two key factors dominating UK politics right now, and it's not clear to me that Labour in particular, and the England opposition in general, can do much at the moment but wait and hope that things change in their favour. The most dominant is certainly Covid. The Government's handling of the crisis hasn't been great, to say the least (in particular, the dithering in Autumn and in the run-up to Christmas last year has proven devastating); but the last few months have seen a change in fortunes, in part because of the successful vaccination programme. It's inevitable that the Government gets credit for that and the Opposition none. I'd also say that, given how badly the crisis is developing in other countries currently, it's making the overall outcomes in the UK look less poor (although "everybody failed" should still not be a convincing excuse for failure).
Oh, yes, and Brexit. Labour was on the wrong side of politics on that one since 2016.* I don't see that changing any time soon, either.
*Not only Labour, of course (see also Lib Dems, Independent Group, etc.)
